John does AMAZING work! He got my Marshall up and running in a more than timely manner. When I went to pick up my amp, he gave me a thorough explanation of the process to diagnose the issue and its origin, what the fix was and what to do moving forward to get the most out of my amp. The cost was more than fair! read more

I have a pristine 1971 Ampeg B-15N that had developed some noise and one of the channels was not working. John went through and tested every component and replaced anything out of spec. He had it ready in two days. I'm the second owner of this amp and I doubt it has ever sounded this good. The noise floor is so low you can't hear it unless the volume is turned up to about 3/4 and even then it is very low. I highly recommend John for vintage amp repair and will use him for any future repairs I need. read more

Would not recommend John. His soldering is clean and his turnaround times are reasonable, but I don't believe he tests his work thoroughly enough. I drove an hour to John from my studio in LA to drop off a 1966 Princeton Reverb with some output issues, hissing, crackling, etc. A week later I received the invoice, paid, picked up the amp and took it home. The issue was not resolved. Took a video for proof. I drove the amp back to John and showed him the video, he apologized and said he would get it right this time, and wouldn't double down on labor costs. I thanked him for that, and dropped off the amp. Two weeks later I got a second invoice requesting additional payment. Confused and reluctant to pay a second fee, I still paid and picked up the amp. This time before driving back home to LA, I took the amp to the local guitar center to test it myself, and the issue STILL persisted after not even 10 minutes of play time. I took another video. Frustrated, I brought the amp back to John and showed him the video. He asked I leave the amp with him a third time. I explained that I do not feel confident in doing so, and I requested a refund on labor since I already paid two invoices for an issue that was never fixed. He was professional enough to agree, but I will not be returning to John or recommending him to any other musicians in my area. read more

I brought my guitar amp to John for service and was happy I found him. John did an outstanding job replacing some of the components and did so on the very same day. The price was very fair and the results are fantastic. My amp sounds great no more hissing and it sounds better than when I bought it brand new a few years ago. I would definitely have John perform any repairs in the future. read more

John is vastly knowledgeable about guitars, amps and pedals! He fixed, maintained and modded my silver face Deluxe Reverb, and it sounds amazing - never sounded better! With that success, I have since brought him my Tele and one of my Strats to swap out the pickups with those he recommended, and replace the neck on the Tele. Again, excellent results: enhanced tone, reduced noise and improved playability. I worked with him to solve a noise issue with my rig, and he methodically worked through the many possibilities and correctly identified that my pedal board power supply had failed. Next up: New pickups for my Les Paul. Looking forward to that! Thanks to John's gifts (and he is gifted), my equipment is beyond reproach, with great tone and minimal hiss/noise. Thanks, John! read more

John serviced and modded my Marshall JVM 410. I'd always struggled with the inherent hiss and noise that came with this amp. Thanks to his mods, the amp is now perfect! Not only did he do the job well, but he did it at a fair price and super turnaround. I will come back again and again! Thank you! read more

John is a gray guy. Fast knowledgeable and really helpful and educational. He'll be helping me with amps in the future again

I was referred to John (Pro Amp Solutions) by Dave and Ralph at Guitar Center. They highly recommended John. I have a Mesa Boogie California Tweed Amp that began to Buzz/Hum. I attempted to trouble shoot the problem, but couldn't isolate a tube, or the problem. I called John. He suggested I take the amp into his shop. When I arrived, John gave my amp a complete check up. He was able to isolate the issue, and fix it. It was a loose connection with the Reverb Tank. John was professional, friendly, and efficient. My charge for Johns service was a handshake. I consider John my go to Amp Repair specialist from now on. Thank You John. read more

Found John through a Google search and couldn't be happier with his level of communication, quality of work and turn around time. Reached out to him to inquire about bringing a vintage Vox Amp and and vintage Selmer Amp back to life and he went above and beyond, delivering exactly what I hoped for. Additionally, he did some spectacular mods on a Fender Princeton that displayed both his high level of knowledge and great ear for tone. I'll be using John for all of my future amp needs and couldn't recommend a better, more qualified guy! read more

Can't recommend John enough. He had my Plexi ready for me the next day and his rates are very reasonable.

My Marshall DSL20CR had a buzzing noise, so I contacted John to fix it. He did a great job diagnosing and fixing the buzzing noise in my Marshall DSL20CR. The amp has no more buzzing, and sounds great! The service was quick and it was a pleasure to work with him. I highly recommend to give him a shot! read more
