Amp Repairs and Mods

We specialize in repairing and modding vacuum tube guitar amps and bass amps. Please note that we work on vacuum tube amps ONLY. We do not repair or mod solid-state amps, effects units, speakers, mixers, PA systems, cables, hi-fi/stereo gear, tuners, or radios--ONLY vacuum tube guitar and bass amps.

Repairs

We can fix practically anything that's wrong with a vacuum tube amp. Here are some of the most common repairs we are asked to tackle.

Mods

It's often possible to improve the sound of a guitar amp by modding it, even though the amp isn't technically broken. Here are a few of the ways we may be able to make your amp sound the way you want it to sound.

The best candidates for modding are vintage amps that don't employ printed circuit board construction. Obscure vintage amps can often be transformed into completely different beasts. For example, it's fairly easy to turn a Traynor YBA-1 bass amp into a dead-on clone of a Marshall JTM-45 or a Fender Bassman.

Even amps with printed circuit board construction can be modded to a surprising degree. Contact us and we'll tell you what's feasible for your amp.
