Guitar fuzz pedal effect. This silicon-based transistor fuzz circuit delivers classic tone with unrivaled versatility. At the heart of this fuzz device lies the Bias control, which limits the amount of current being fed to the transistors for a gated and velcro-like fuzz tone. It simulates the failing battery syndrome making your signal sputter out prematurely and provides for a grimier experience. 9V DC adapter is not included. Dimensions: 4,8 x 6 x 11,1 cm. Weight: 217 g.
