Harmonic Fuzz. At the heart of the circuit is a NOS PNP germanium transistor coupled with a silicon NPN transistor. We found the magic pair to give you the sweetest harmonic generation and most dynamic playing response. The Karma Suture is capable of a wide range of sweet, even-order harmonic distortion responses – from heavily saturated fuzz tones, to big and open overdrive, to a sparkling boost. And no matter how you have the pedal set, the tone and response is always alive, sensitive to your every playing nuance. • MFSKU Karma Suture Ge • UPC 853710004222
