Hartman Electronics is a boutique guitar effects pedal builder based in Berkeley, California. The brand focuses on recreating out-of-production classic circuits — particularly early germanium and silicon transistor fuzz designs — using hand-selected components, N.O.S. (new old-stock) transistors where appropriate, and hand-tuned assembly alongside modern, plated-through-hole PCB construction.

The lineup spans fuzz, boost, compression, modulation, and overdrive. Notable pedals include the Vintage Germanium Fuzz, the Silicon Crystal Valve and Germanium Crystal Valve (inspired by Solasound SupaTonebender and Vox Tonebender MKII/MKIII circuits), the SFZ Dual Fuzz, a Compressor based on Dan Armstrong's Orange Squeeze, an Analog Flanger inspired by the '70s Electric Mistress, an LM308 Op-Amp Distortion, and a Vintage Germanium Boost built around PNP germanium transistors. The Envelope Filter was developed in collaboration with guitarist Mark Karan.

The pedals are distributed through major retailers including Guitar Center, Musician's Friend, and Reverb, and have found an audience among players looking for faithful, hand-built takes on vintage stompbox designs rather than mass-produced reissues.

Hartman has 11 products cataloged on Equipboard, including Fuzz Effects Pedals, Flanger Effects Pedals, and Distortion Effects Pedals. Their gear is featured by 7 artists, with the strongest followings in Rock, Funk / Soul, and Jazz. Notable users include Max Becker, Paul Jackson Jr., and Sam Wilkes.
