Demo sound of Jimi Hendrix Fuzz JH-2:
The Jh-2 has a tendency to fold in on itself and gives the impression that unity gain is unattainable: the secret? Roll off your tone knob to unleash the unbelievably rich harmonic distortion of this sick, sick, sick beast. The demo pays tribute to the fuzz gods of my youth: the Jesus and Mary Chain and Dinosaur Jr. Hope you enjoy.
