Amplifier maintenance, repair, and modifications

Our experience in repair began with vintage tube amplifiers and has since expanded into virtually all areas of amplification. It continues to this day to be the busiest department of the shop. K.I.A. services guitar and bass amplifiers from vintage and modern tube amps.

Labor: $50/hour

Please note: At this time, due to increased demand, we are unable to take on repairs for pro audio, stereo equipment or non-guitar/bass amplifiers.

As well as repairing, Joel Amsden manufactures totally Maine-made, military spec, hand-wired tube guitar amplifiers under his brand, SOMA Amplification.
