Sam’s Guitar Amp Repair is the San Francisco home of Mollica Amplifiers, where technician Sam Mollica handles guitar amp repair alongside his work building custom hand-built tube amps from scratch. Operating out of California’s Bay Area, Sam brings a craftsman’s perspective to amplifier repair that sets this shop apart from standard electronics repair outfits. Because Sam designs and builds his own tube amps by hand, he brings a deeper level of circuit knowledge to every amp repair job that comes through the door. That kind of hands-on experience with tube amp design means he understands these instruments from the inside out, not just as a repair tech following a schematic.

For guitarists in San Francisco dealing with a malfunctioning combo amp, a blown head, or any kind of tube amplifier trouble, Mollica Amplifiers offers repair work backed by genuine builder-level expertise. The shop also sells gear through its online store and shares audio and video content for those who want to hear the work in action before bringing something in.
