Acorn Amplifiers is a small, Atlanta, Georgia-based builder of hand-wired tube amplifiers and effects pedals. Each amp and pedal is assembled in-house from individually measured components, with the company positioning itself as a boutique operation run by musicians and tube-amp technicians rather than a mass-market manufacturer. Cabinets and head shells are built from Baltic birch and exotic hardwoods.

The brand is best known on the pedal side for a lineup of fuzzes, distortions, overdrives, and preamps, including the ADHD Synth Fuzz, the Mind Killer dual distortion, and the TMA-1 fuzz. Their tube amplifier range covers both guitar and bass, designed around simple, carefully voiced circuits aimed at players looking for hand-built alternatives to production amps.

Acorn Amplifiers has 8 products cataloged on Equipboard, including Fuzz Effects Pedals, Overdrive Effects Pedals, and Guitar Preamp Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Gustav Larsson and Emily Hopkins.
