1966 Fender Super Reverb

The Four-Corners region is incredibly fortunate to have Robert Evans of Audio Atelier as a highly qualified tube amp specialist. Anyone familiar with vintage tube amps can appreciate the rich and unique character that makes these amps so special. However, these aging amps do require occasional maintenance and repair to truly harness their full sonic potential.
 
After playing my Super Reverb for about a year, I noticed several issues mainly with the quality of the sound coming from my amp. In addition to some humming noises, the tone sounded less full than when I acquired the amp in the summer of 2015. It was still a vintage amp and sounded good, but not great.

I play a lot of blues-based rock stuff using a variety of pedals and loops. I love this amp because the four ten speakers enable the loops to sound so large. Anyway, as the sound degraded over the year of my ownership, I figured it couldn’t hurt to get the amp checked out by a professional.
 
I brought the amp into Audio Atelier in the late spring of 2016 and a few hours later received a call from Robert Evans. We discussed the issues going on with the amp, my playing style, and the ideal sound I wanted to achieve from the amp.
 
After a few days of working some magic (replacing output tubes, power supply capacitors, etc), Robert returned the amp. I immediately noticed the humming sounds were gone and the overall tone of the amp sounded better. He included a full write up of the repairs and I found his fee very reasonable.
 
Unfortunately, as I played the amp over the following weeks, I was not entirely satisfied with the sound. The Super Reverb can innately have a very boomy sound and it seemed the amp was breaking up when I desired more sparkling clean tones in the mid volume range.
 
Robert suggested I bring the amp back in and play around with several different tubes. He patiently installed a few different tubes for the gain while I noodled around experimenting with the different sounds. It was very cool learning about these tubes and how they are all so unique in the way they color the sound of the amp. One tube simply blew my mind with its crystal clean tone and the dynamic response when playing. This was it! Instantly, my amp sounded amazing, probably the best since its birth in 1966 (maybe even better!).
 
I can’t thank Robert enough for taking the time to go above and beyond in his work. We are very lucky to have such a knowledgeable and qualified amplifier specialist locally here in Durango, Colorado. Thank you Robert for being so passionate about these amps and ensuring we all enjoy these vintage sounds in their full potential.

Fender Hotrod Deluxe

I have been using tube guitar amps for over 30 years as the guitarist for The Lindells. They need wellness checkups and repairs routinely. I had a few non professionals work on my Fender Hot Rod Deluxe. It had some problems with humming and intermittent signal. I took the amp to Mr. Evans and he not only fixed the problems but improved the sound of the amp overall. The next thing that happened, less than three weeks after the original work was complete, was that the amp developed a worsening hum, and an electrical fire smell. Power down! I took the amp back to the shop and Robert found a bad tube (from the manufacturer) that was shorting out. I had the amp in around 11:00 am and he called me by 4:00 pm the same day to let me know it was ready. Great service and great communication. I have a new amp tech! Yay!

Fender Hotrod Deluxe and a Cougar 15

I've taken two of my amps to Robert and both of them have come back sounding better than the day I bought them. Robert uses high quality tubes and parts and knows what he's doing. I would not take an amp in need of repair to anyone in Durango, CO or the surrounding area other than Robert. You can tell that Robert has a passion for his work from the moment you meet him.

Dearmond R15T Amplifier

Living in S.W. Colorado is sometimes difficult to find specialized talents. Tube amplification repair is one of these. 15 years ago I bought an old DeArmond Tube Amp for $20 at a yard sale. Now I have a fully functional piece of musical history that sounds incredible thanks to Robert. Now I call my amp Lazarus.

Danny Samons

Note: Dearmond R15T - a very rare and highly sought after amp. Some consider this the "Holy Grail" of small amplifiers. It is known for it's incredible tone. This particular amp has the well known "over-sized" output transformer, which most experts feel is the key to this amp's incredible tone.

 

Fender Blues Junior

The Fender Blues Junior that you repaired sounds great! Thank you for your rapid and professional service.

Simply said…. this is how all customer service should be. I brought the amplifier to you on September 5 around 11:00 am and received an e-mail from you on September 6 at 1:04 pm saying it was repaired. Seriously 26 hours later it was ready to go. Since receiving it back I have played it almost every day… NICE.

Thank you for a great experience.

Fender Vibro-King

The Vibro-King is sounding better than ever! I've done two gigs with it and have not had a problem with blowing fuses. It seems to have gained some power and clarity as well. The floating 3" screw probably wasn't helping much. It had probably been there since the amp was manufactured.

As always, the promptness and professionalism of your audio service is tremendous.

1964 Fender Vibro Champ

I have owned and played a 1964 Fender Vibro Champ Amplifier for years. When I bought it, there was an aftermarket replacement speaker in it that did not sound very good to me so I replaced it with a Kendrick speaker that sounded better. Over the years of playing the amp, the tone degraded to a thinner, weaker sound that was not satisfactory regardless of the guitar played through it. I took it to Robert Evans/Audio Atelier for repair. He replaced the old capacitors, some of the tubes, and he suggested that a larger output transformer would give a tone with more clarity and fullness. I readily agreed and it was ordered and installed. Robert also suggested that I might want to try a different 8" speaker as the existing one had an unusual crimp in the paper cone, which it did have. I chose to try a new Celestion speaker. The little amp sounds much, much better than it ever did before. It has a great clear, clean tone and when cranked above 7 or 8 it has a smooth distortion without harshness.

 Fender Twin Reverb (clone)

Robert did this most amazing work on my rare stereo pro valve amp, so I brought him this other amp to work on... The amp is a 2x12 combo. The amp basically doesn't exist. No specs nothing. It was a huge pain... What came back to me is unbelievable. The most amazing sounding amp ever. Im blown away. I don't think you could buy an amp sounding this awesome in a store... if you could it would be a small fortune. Don't know if anyone else could have done this. I own this amp, wow. Thanks Robert. I'm a believer. Go to Audioatelier.com ...Your tube amp will sound real good.

Michael Matovich

"Mike brought in a well-made, Fender Twin Reverb clone, with no identifiable branding and of course, no schematic available anywhere. The power transformer had an open primary winding. So while it was possible to make an educated guess as to the voltage requirements for the tube circuits, and thus to specify a replacement transformer, the solid-state switching and tone circuits had unknown voltage requirements. And just about no tube amp replacement transformers have windings to supply solid-state devices. After much research I found a transformer that met all requirements, and experimented with the solid-state power supply voltages till we got it right. The transformer also provides some additional heft and dynamic range to the amp, and, blessedly, fits into the chassis and enclosure with perhaps a millimeter to spare." - Robert Evans

 

JCM900

I got Roberts name from a local music store who I had look at a used Marshall JCM 900 that I purchased which sounded okay when I test drove it but when I got it to our practice room it was crackling, had poor gain and eventually just stopped working altogether within an hour or so of plugging it in.

So I took it Robert who straight off said he had to leave town the next day but would get to it as soon as he got back which he did, he gave me a diagnoses of what was wrong with my amp some of which I didn't understand but he explained it to me in a way that made sense. So he gave me a couple of options for repairs and cost I already thought I needed a new amp so the estimates on repairs sounded like a better option than looking for and purchasing a new amp.

He got it all done I got it back to the practice room and couldn't have been happier with the sound, Robert suggested I bring it back after 15 hrs of play time so he could rebalance it I did that and it sounded great for the last two and a half years, he gave me another estimate on how many hours of play time it would be before it needed to be serviced again and right around then it did need to be looked at again I took it in it was a one day turn around and it's sounding sweet again. Thanks Robert

1965 Fender Twin Reverb Reissue

This was my workhorse amp's second visit to Robert's shop. It was tired and noisy. My needs had evolved to where I have to rely on the amp's original clean tone for jazz, but need punch and presence to play blues or with horns. Robert came up with a great tube-set recommendation and tune-up that really give me the tone this amp is capable of. Thanks, Robert.

Geronimo 55 Lead

Hey Robert,

Well, got in a gig with the PA (where I was running sound) and it worked well! Don't want to jinx it; have two gigs this weekend where I'll be using it and will give the final verdict after that, but it seems the TLC may have extended its life for another season.

The amp continues to astound! Both gigs last weekend; the guitar sounded SO good... 'roared' is the best word I can think of... I see why they call those tubes Gold Lions... I haven't really 'gotten', completely, the change in output; don't really KNOW if it's higher or lower, but do know it's a little different.... isn't intuitive for me yet. Still fiddling with the volume on stage to dial it in... but what a fun game to play!

I'll write again next week and let you know how this weekend goes

Be well!

Fender Hotrod Deluxe

Dear Robert,

I couldn't be happier with the work you have done resurrecting my Fender Hotrod Deluxe amp. Years of Colorado and New Mexico "road" work had taken their toll on this amp. Cleaning and lubricating controls, deoxydizing and re-soldering loose contacts, are probably typical amp repair duties, but then you took it a step further with your "Atelier's" recipe of hand picked tubes and high quality capacitors leaving me with an amp that would rival a "Mas 38 " on steroids! With the tone controls at 12:00 I have an easy to find mix of shimmering highs with a perfect low end compliment! No more "scooping" mids to get rid of that "honk" sound all guitar players hate!! My mid range now adds presence, instead of "honk"! This amp now delivers plenty of headroom with balls to spare! Combine that with a compressor and a Tube Screamer........forget about it !!!

I was almost convinced that I needed some $3000.00 Mesa, or Dr. Z amp to achieve the tone I need for the kind of stuff I play. Turns out all I needed was the right recipe of tweaks and tubes from our friendly neighborhood ATELIER ! Thanks again Robert for what you can do for hopeless tone addicts like myself!
Sincerely,

Neil Nelson (The High Rollers)

P.S. I have a poor, tone sapped Marshall JCM 850. I can't wait to bring you two together !!!

90's Fender Twin

I actually stumbled into Robert by accident. I was rock'n out one day as I normally do, when out of nowhere the jewel light on my 90's Fender twin went out, and the amp went silent. I brought it down to the local Fender shop to be repaired, and shortly thereafter got a call letting me know the job was beyond the skill level of the shop repairman. I asked if there was anything I could do, and was told there might be one person I could contact. Robert. I'll tell you right now that's one email I'm awfully glad I sent.

Looking under the hood, Robert was quickly able to determine that I'd blown the power transformer. He presented me with a few options (the cheap way, the fender way, or HIS way), and this is where I became the luckiest guy on earth. You see nobody @ the fender shop told me anything of Robert but his email address, and he was out of town when the I dropped the amp off at his workshop, so I'd formed the impression I was getting an electronics repairman not a Tube Amp Guru. Little did I know……

Upon getting Roberts thoughts on the nature of my problem, the state the of my amp as a whole, as well as fender components, I did what any sensible person would do and Ýjust decided to let Robert have his way with it. I answered a few questions about my playing style and off he went. It wasn't long before Robert had replaced the Power Transformer, Upgraded the Tubes and Capacitors, and performed a whole bunch wizardry that only he could properly explain.

The results? Too good to be true. I play a PRS single-cut, so to say my pick-ups are hot is the understatement of the century. I don't however play metal. Finding an amp that would tame them into producing a rich, every notes clearly audible, yet completely overdriven tone was no easy task. The twin came close, Roberts tweeks? NAILED IT! First thing I noticed when I turned the amp on (besides the amp turning on), NO MORE HUM. It wasn't even a request, or something I thought you could fix, but fix it he did. Immediately I could hear added warmth to my tones, saturated with harmonics that were just not there before, not to mention sustain for days. I like to hold notes too long and ride feedback to the breaking point, in this regard, the amp delivers above all else. My attacks all sound punchier, with every subtle little pick noise coming thru, and no matter how hard I crank it the tone never breaks down. In a word, BLISTERING! I just can't overstate how truly grateful I am to you Robert, my amp sounds better than I could have ever hoped. Only wish I had something else to let you tinker with.

Gibson BR-9 Amp

Robert,

I wanted to thank you again for helping resurrect some of my old vintage amps.

Thanks to you, I have finally been able to diversify the tone and character for amplifying my harmonica.

My 1950's Gibson BR-9 amp still sounded pretty good after all these years, but had developed an extremely annoying (and loud) hum that drove me my crazy. I dropped it off to see if you could help me out and 1 week later its a whole new amp. It is totally silent when not playing, and a little screaming machine when i want it to be... I can't believe how quiet it is...sometimes I have to double check just to make sure its still on.

I also appreciate your help with my other little tube amp, the Voice of Music. I love all the tone and distortion I can get at a low volume with this thing... I can get all the warm Chicago Blues Tone with this amp without rattling the walls....my wife and my neighbors thank you too!

Thanks again for all the great work - I couldn't get half the tone out of these amps without your help.

Cheers. Randy

 

Valco/Oahu Amp

I want to thank you for doing such an incredible job fixing up my old Valco/Oahu amp. I asked you to help make it a harp amplifier; and you created honkin' blues machine! I can't believe you were able to get so much tone and volume to fit in that little cabinet. It sounds incredible. It varies from a clean and crisp sound, to a warm and fuzzy tone, to a down-right dirty bluesy feel.... at any volume. It is perfect for harmonica.

I also appreciate your communication with me and your suggestions throughout the rebuilding process. I couldn't be happier. It is great to know that we have such a highly skilled tube amp specialist in the four corners area.

1965 Fender Deluxe Reverb

I didn't realize that my old Deluxe Reverb had been modded before I got it with a non-original type power transformer; the amp distortion was ugly and at far too low volumes; especially with humbucker-equipped guitars. Robert diagnosed the problem and installed a new original-spec. transformer, new tubes, and biased the output tubes. The amp now performs like it was designed with more headroom/volume without distortion and with much greater chord and individual note clarity.

Thanks Robert,
Art Collins

1974 Marshall Super Lead
Fender Hot Rod Deluxe

Hello Robert,

Just wanted to say that I am very thankful for the repairs (upgrades) you did to my 1974 Marshall Super Lead and Fender Hot Rod Deluxe. Not only are the problems fixed, but both amps sound much better than they did before. Hum/Buzzing fixed, squealing fixed, much louder, the Fender sounds much more vintage, and the Marshall sounds even more perfect than it did before. New capacitors and tubes made a world of a difference in all aspects. I am more than pleased with what you have done, and will not think twice about bringing my amps to you for a repair or dialing in the ultimate tone (although I can't complain about what I've got now!). Very impressed by the speed and thoroughness of your work as well. Thanks again for your incredible work, and it was great seeing you at our gig!

Mesa Lonestar Special 112 Combo
Paul Reed Smith Sweet 16 Head

After a bout of fuse blowing on my Mesa, I relied on Robert to diagnose and repair my workhorse. Working closely with the engineers at Mesa, Robert was able to diagnose a very complex circuit problem and promptly returned the amp in perfect working order. I also had Robert inspect, re-tube and bias my Paul Reed Smith amp with awesome results.

Diagnosing and repairing circuits is expected of any amplification expert. My surprise was that Robert not only took the time to listen to my description of the sound I was searching for, but was able to recommend and perform tone-enhancing modifications to meet my specific needs to not only my amps but my guitar also!

We are truly fortunate to have a person with the combination of skill sets Robert possesses: electronic circuit authority, audio aficionado, music connoisseur, music and guitar history buff, tube history critic, analog theory maven, vast understanding of audio production and people skills (to name a few). There are very few people with this combination of skills anywhere.

'Delighted' is an understatement of my experiences with Robert. I am thrilled to have a mentor such as Robert in my search for the 'Holy Grail of Tone'.

Fender Blues Deville 2-12

Robert,

Thanks for getting the amp up and running for this past Labor Day weekend! That was a big weekend for the band (an opening slot for a national act, as well as some other good, high profile gigs) and I really, needed my amp to feel comfortable with my sound for those type of jobs.

Not only did you fix the amp, the work you did on the amplifier absolutely improved the sound of the amp. The amp (mid 90's USA-made Fender Blues Deville 2-12) has always been a solid working musicians amp, performing well and reliably at countless gigs, but not too spectacular on tone. With the meticulously matched tubes you installed, as well as the desperately needed maintenance/TLC, the amplifier's sound has really taken on new and wonderful dimensions in sweet, singing overdrive as well as a much finer clean tone. Where as I used to use the 'master volume' channel to get the type of overdrive my guitar work requires, I am now getting an even better overdrive tone on the 'normal' channel, with the added benefit of good Fender sparkle on the 'clean' sections of my work when I back the guitar volume off some. (which I wasn't able to create using the master volume channel). The amp is taking my 'stomp box' pedals well, too, sounding even better than before. And the amp is back to its old reliable self again. The best of all worlds.

So thanks again for getting this amp intoa premium working condition. You've certainly earned an appreciative and satisfied customer.

Fender Twin Reverb '65 Reissue

I had heard Robert's work on several amps, and was curious what he could do in the way of upgrades to a stock Fender Twin reverb '65 reissue, built in the early 2,000's.

I wasn't looking to stray too far from the stock circuitry but wanted something to augment the sound of an already very nice performer. We discussed several options, and settled on a matched set of output tubes, leaving the rest of the unit original.

Robert's choice of tubes, and biasing, gave this amp incredible bite and presence using more aggressive picking, with increased headroom. At the same time, it shows warm, subtle colors when I back off. TOTAL tone and flexibility.

Thanks, Robert.
Chris Beller

 

JCM 800

Robert,

I am amazed at how my amps sounds! It is no longer a "one trick pony". It sounds equally spectacular over driven as it does clean and with a little volume control, can transition from one to the other seamlessly. Also, the KT66 valves have a unique voice, so I don't sound like everyone else.

Thanks!
Rob

Carvin Bel Air 212

I bought a Carvin Bel Air 212 tube amplifier from Robert. This had been his personal "shop amp" and as such he had upgraded all the preamp and power tubes with his own personal favorite tubes. He also performed a full set of "Hasserl mods" to broaden the tonal palette of the amp. WIth all of these modifications, a good amp has become a great amp with versatility to spare. After gigging with it a few times I can honestly say that I never thought I'd be able to buy an amp that could sound this good or be this fun to play for such a reasonable price. My advice to any owner of a tube amp, particularly those who feel that their amps could be improved in any way, is talk to Robert to see what he would recommend. My guess is that you would be happy you did.

Thanks Robert!!
Hap Purcell

 

Acoustic Amp

I'm not a great guitarist, but I enjoy playing whatever I am capable of. This little Acoustic Amp was a birthday present from my brother and unfortunately I "burned up" the transformer at the last session I played with his band before I left Switzerland to move to Durango.

Therefore it means a lot to me and I am very grateful to you that you brought it back to life and made it sound even better than before. I'd like to thank you for all the hours and work you've put into it, which made me a very happy customer! 

Thanks again,
Baudi Shellnut

 

Allen Guitar Amp

Wanted to get back to you regarding the transformer upgrade and voicing changes we did on my Allen amps. The Brown Sugar has blossomed beautifully and now paired with a 1x12 EV cab it has become my favorite club sized amp to date. The re-voicing you did on the smaller amp dramatically improved the treble response and makes the amp much easier to dial in. I also can't tell you how much I appreciate the amps being returned clean, tightened up mechanically and re-biased. I greatly appreciate your knowledge base, professionalism and excellent ears.

Thanks Again,
John Massone

 

Fender Blackface Super Reverb

After an output tube blew on my amp, Robert suggested two output tube pair alternatives for replacements. He then installed the new matched pair of output tubes that I selected and set the bias on them for the best performance. Also he installed a necessary new phase splitter tube. The amp was much louder with more headroom, clarity, and punch. It is much more responsive to my pick attack. I didn't realize the amp could sound this good!! 

Thanks Robert,
Art Collins

 

1990 Fender Twin

After years of performing with my Fender Twin, it was in need of repair. I heard that Robert Evans was THE tube amp specialist and I contacted him. After Robert diagnosed some of the amp's issues, he gave me options as to their repair. I had Robert overhaul the amp, involved cleaning the circuitry, replacing speaker wire, capacitors, resistors, power tubes and the reverb tank.

When it came to the pre-amp tubes, Robert asked me about the specific type of sounds and tones I was seeking when improving upon the amp. Based on that discussion, Robert chose various tubes that he suggested along those lines.

Then through a brief session he had me play the guitar through the amp while he sampled different tonal tubes. In his workshop I was able to select the exact tubes I wanted for this amplifier.

We dialed in the amp through a process that I could not have done otherwise. As a quality technician, Robert listens as closely to the internal workings of tube circuitry as he does to the customer's needs.

I've had Robert work on additional amps of mine over the years. And when asked, I have gladly passed along Robert's phone number to musicians who use tube amplifiers.

Robert, thanks for your great work.

Dean Markley Signature Series 60 guitar amp

I have this Dean Markley amp, that I had given up on about 15 years ago. It had no clarity anymore and it sounded like a chainsaw when you turned it on. I had taken it to two other shops and it came back sounding the same. I heard about Mr. Evans at a guitar jam and decided to give it one more go before throwing it out the window. I could tell from our first talk that this guy probably knows what the hell he's talking about. I got the amp back in a timely fashion and it sounds great. It has a clarity and bite that seems to be better than it was born with; and it doesn't make a sound you don't tell it to. You need an amp fixed (correctly), this is the place to take it.

Thanks again
Mike Botts

 

1959 Fender Champ

Robert,

I worked on the Champ some more this week. The speaker was attached loosely with Bondo and three screws if you can believe it. I took the whole thing apart and drilled new holes and mounted it nicely. I think the low strings are much better and it got rid of some other artifacts I was hearing when it was played loudly.

Thanks for working on my new ebay purchase 1959 Fender Champ. Thanks a lot for your dedicated effort to sort out the power issues and replace cap's and resistors. It is now just what I thought it should be. It's great that there is someone in Durango servicing musician's amplifiers with your knowledge and meticulous attention to detail. I appreciate it.

Regards,
Marc Katz

 

Ampeg B15 N Flip Top Bass Amp

On the advice of a band mate, I called Robert Evans the "amp doctor" to get his opinion of the amp and to see if he thought it was worth trying to restore. I took the amp to Robert's shop where he immediately started taking cover plates off to look at the inner workings. After a few moments, he commented that this was his favorite variation of the Ampeg B15 N Flip Top and thought it to be a 1961 edition. He also noted that it was in very near original condition and thought it was well worth some attention to get it running again.

A few weeks later I found myself back at his shop to give the amp a listen. I brought my number one bass with the best vintage tone to plug in with. Power on. Standby on. No noise. Beautiful tone. I couldn't believe it. I don't understand how all the little parts and wires make such a beautiful sound, but Robert does. He turned a piece of garage sale junk into my studio recording bass amplifier.

Robert has a very in-depth understanding of electronics and has since helped me with a newer tube amplifier. I also trust him with the ideals of preserving the vintage integrity of a classic piece of gear.

Thanks Robert.
Hal Lott, bass player

 

Johnson Marquis JM 60 Amp

This is mid-priced modeling amp that puts out 60 W. It features a number of amp models and effects, and relies on a single tube pre-amp. When the amp stopped working, Robert fixed it quickly and professionally.

But the real news is that, for about $ 20, Robert replaced the original tube with one that transformed the sound of the amp. It now has an immediate attack (using hotter pickup guitars), and a warmth and depth it always lacked.

Thanks Robert.

1972 Fender Super Reverb Amplifier

I'm a rock and blues guitarist, and I asked Robert Evans (the Audio Atelier) to do some work on my 1972 Fender Super Reverb amp in May 2007. The amp was working, but it was fairly noisy, it had blown a fuse recently, some of the controls didn't seem to be working effectively, and I was worried it might be on the edge of a breakdown.

After communicating with me about my style of playing, tone preferences, and what I wanted out of the amp, Robert spent two hours with the amp and then called me in to test it. I immediately noticed the following improvements:

• The amp was noticeably quieter..... the background crackling and hum were gone.

• The amp had more clean headroom, and was louder at comparable volumes.

• The bass control, which previously was effective only up to 3, and then very muddy from 4 on up (a problem I have heard from other vintage Super Reverb owners), was much more effective. Settings at 4 and above had a gradually increased bass response without being overly muddy.

I was very pleased with Robert's work on my amp, and with his knowledge and expertise with tube amps and sound quality.

Thanks again, Robert, and keep up the good work. Cheers,
Larry Carver (Durango, Colorado)
