Acid Guitar Electronics is a boutique pedal builder based in Raleigh, North Carolina, specializing in handmade guitar and bass effects pedals. The brand focuses on classic fuzz and boost circuits with its own modifications, producing small-batch, hand-built units.

The lineup centers on the Acid Face, the brand's take on the iconic Fuzz Face circuit, offered in both silicon and germanium transistor versions. The Acid Face is notably louder than a standard Fuzz Face and features an internal bias adjustment for fine-tuning. The Thorazine Boost is a versatile two-knob pedal capable of producing clean boost, overdrive, and fuzz tones, designed to work well with both guitar and bass. Acid Guitar Electronics also builds a germanium-transistor Naga Viper clone, a treble booster based on the Rangemaster circuit. The pedals are available through select dealers and on Reverb, often with waitlists due to the limited production runs.
