JAM Pedals Octaurus GRN
Jam Pedals · pedal
The JAM Pedals Octaurus GRN is a germanium-based octave fuzz pedal from the Greek boutique builder JAM Pedals, combining a fuzz circuit with an upper-octave harmonic effect using germanium transistors for warm, vintage-voiced character. The germanium topology produces a soft, warm fuzz with a natural upper-octave shimmer suited to psychedelic rock, blues, and experimental styles where vintage harmonic character is desired. JAM Pedals hand-builds all pedals in Athens with individually selected germanium components for consistent performance.
