I think they are closed. I came by a couple months ago and also came by just now but no one is here. Left the message via phone last time but no answer. And now goes to beep sound. read more

I plan on taking my Mackie 12Pro and an electric guitar to have them fixed since he did a great job on my other guitar

Called today to ask about bringing in my Marshall 9200 power amp for service. I am a past customer and had great service last time around a few years ago. Anyway I looked them up again as a repeat customer and gave them a ring. The fellow who answered the phone acted as if I was bothering him calling and was condescending, told me I could not drop my amp off to him without an appointment and that would be no sooner than tuesday at 12:30pm. I tried to explain I will be out of town for the next few weeks and as he was there could I just stop by and drop it off he was basically like, no you can't, too bad and btw it would be 2 weeks to get to it which he seemed to take great pleasure in telling me. (I was actually going out of town and that would of been fine with me). Anyway very dismissive and arrogant on the phone. Surprised as last time I had these guys work on one of my amps it was fine and they do seem to have good reviews, maybe I caught him on a bad day? Brad read more

Thank you Ryan, for taking the time to help me with my Mesa Boogie Subway bass amp. Its 6 years old, and just needed the various contacts cleaned! Now that i know who you are,and where you are located, i'll spread the word, Thanks again! read more

Update! Took my super strat here to have a pickup installed and set up. The guitar came back perfect, the action was better than ever and the intonation is perfect! This place does great work! Took my Friedman small box here for a tube change and bias. Talked with Ryan who understood the exact tone I was looking. He recommended Siemens tubes and now the amp screams better than when I first got it. Amazing how much difference the right tubes and bias can do for an amp! read more

Had a late 50's/ early 60's premiere guitar amp in desperate need for help. Ryan was super helpful and got it back to working order. The amp sounds great and he was awesome to work with.

Excellent work. I hadn't taken much care of my amp (Fender 72 Blues Deluxe tweed) for years. He put in extra work to make sure it was working correctly and sounding like it should. He knows his stuff!!! He only accepts cash, so be prepared! Oh... he also has a warranty! Legendary service. read more

This is a great little shop. I took in a hodgepodge Super Reverb with a transformer and other small issues. They were able to work through a fairly complicated amp. read more

I had the good luck of running across Raul's amp repair service when my hand-wired Fender Champ was acting up. It was hissing and occasionally sound levels would drop off dramatically. I was this close to selling and replacing. Within minutes of arriving, Raul took off the back cover and knocked a plastic pen around in there and immediately identified the source of the problem as the crappy soldering job done at the factory. He showed me there were actually a couple of points with literally no solder holding the wires down. He chuckled and told me it looked like this one had been made on a Friday when they couldn't wait to leave the workshop for the weekend. Raul whipped out some solder and had me on my way within 20 minutes with an amp as good as new. Now.... I get that this was unusually good fortune to find him with the time to do that on the spot so while it's not something I would expect every time, it truly is a pleasure to deal directly with someone who knows their craft like the back of their hand. Thanks Raul! read more

My amp was in some serious bad shape and they took it right in. Had it show ready and it's running better then it ever did! Great customer service! This will be my go to for repairs! They understood the urgency of my situation and went above and beyond what I expected ! read more

I brought my 25 year old guitar in for buzzing on several frets. The gentleman was able to quickly and accurately diagnose the problem. He fixed all of the frets, polished the frets and adjusted the neck. The repair was timely and very well done. My old guitar is now better than new!! Ty!! read more

Ryan did a rush order for me 2 days before an event and did a fantastic job! I recommend going to him. Professional, kind, and does a job well done. I will be returning back! read more

I have had guitar work done at a few other places in the past and none of them took the time or had a real care for my instrument. However, Raul is quite the opposite. He ACTUALLY cares! The attention to detail in his work is like no other. He inspects everything inside and out! Down to the finest detail. I have had two guitars worked on from Raul. Upon returning the instruments to me, the guitars felt and sounded better than when I first took them out of the box. The playability is phenomenal! I could not recommend this place enough for all your instrument needs. I will definitely keep going back for as long as this place is around. read more
