JRS Musical Instrument Repair & Sound Services

JRS Musical Instrument Repair & Sound Services saved my Marshall TSL122 combo. My amp suddenly went down (hum but no guitar signal), and after calling around, I found that a lot of places either won’t work on tube amps at all or were quoting wait times a month+ out. JRS was the complete opposite — they diagnosed it quickly and had it repaired next day. The issue ended up being the HT fuse (T1A). Simple fix, but they found it fast, explained what was happening, and got me back up and running without any runaround. Great communication, fair pricing, and super fast turnaround. If you need amp work done, I’d absolutely recommend JRS.

Jack is the real deal. He knows vintage tube amps inside and out and approaches the work with serious attention to detail. Straightforward, professional, and clearly experienced — no guesswork, no fluff. He takes the time to explain things clearly and focuses on doing the job right instead of pushing unnecessary work. It’s rare to find someone who actually understands these older Fender circuits the way he does. If you care about your gear and want it handled properly, Jack’s your guy.

Jack is one of the best guitar guys I have ever dealt with. This guitar I just purchased had some major work needed. He changed the Locking nut, Upgraded the Trem, upgraded pickups to 2 Seymour Duncan humbuckers that sound amazing, upgraded to CTS pots, all new wiring, new input jack. A full setup in D standard as requested and now this thing sounds and plays amazing. If I could give 10 stars I would and I will no longer be taking my guitars anywhere else but here!

I wanted to modify my tele-style guitar because it was buzzing a lot and lacked clarity and depth in sound. Jack worked on my set up, rerouted my guitar, swapped out the pick ups, added stronger POTS, put in a new jack input, and switched from a 3 way to 4 way selector. He had to modify the bridge and control plate and do a lot of electrical reconfiguration to make everything right. The result is the action is greatly improved and my guitar sounds 100% better. If you have guitar problems, take it to Jack. He'll do a great job.
