I am a gigging musician, vintage amplifier collector and an amp tech. I know tone, and I can get you where you want to be. I primarily work on VINTAGE amps. This includes MOST pre-1980 makes and models.

Regarding newer amps, I do basic service and repairs on most makes and models of post 1980 TUBE amps, including Acoustic, Mesa Boogie, Marshall, Fender RI and Custom Shop Series, Boutiques (Victoria, Bad Cat, Clark, Holland, etc.), Crate, and Peavey. I am selective about what I work on, and how much workload I take in. By doing this, I can keep the turn-around time as short as possible.

I do NOT repair the following: BUGERA AMPLIFIERS, PA gear, Solid State rack effects/rack gear (tube rack gear on a case-by-case basis), newer effects, solid state amplifiers, guitars and other non-amplifier related gear.
