The JamPedals Eureka! is a silicon-based analog fuzz-distortion designed to combine the singing midrange of germanium fuzzes with the grit and fullness of classic Muff-style circuits. The result is a versatile and expressive pedal capable of delivering articulate overdrive tones, thick sustaining fuzz, and everything in between. Utilizing silicon transistors in a proprietary architecture, the Eureka! offers a distinctive tonal character that adapts beautifully to any guitar, amp, or pedalboard setup. The onboard three-way toggle switch introduces incremental bass boost (+0 / +1 / +2), making it ideal for both single-coil and humbucker guitars or for adding low-end weight to solos. The Level, Tone, and Gain controls provide precise tonal shaping, from open, gritty textures to compressed, saturated fuzz tones. The Eureka! is true bypass, runs on a 9V battery or 9V DC adapter (tip-negative), and draws only 8 mA. Hand-built in Greece, it reflects JamPedals’ dedication to boutique craftsmanship, sonic integrity, and distinctive visual artistry. Founded in Athens, JamPedals is a boutique effects company known for its hand-built analog pedals, each uniquely painted and tuned to deliver musical warmth, dynamic response, and visual individuality.
