Catalinbread Karma Suture GE
Catalinbread · pedal
The Catalinbread Karma Suture GE is a germanium harmonic saturator and fuzz pedal from Portland, Oregon, using germanium transistors to produce rich, warm harmonic distortion and soft clipping character with the organic, dynamic qualities of germanium components. Covers the range from subtle harmonic enrichment through full-on warm, organic fuzz saturation. The GE designation indicates the germanium transistor implementation versus a silicon alternative. Suited for blues, Americana, and vintage-inspired applications where the organic warmth of germanium saturation is the goal. Made in Portland by Catalinbread.
