Mosferatwo Pedal Circuit Design The Mosferatwo is not your typical overdrive pedal. Its unique sound comes from its carefully crafted circuit, designed entirely with MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) technology. MOSFETs are used throughout the pedal. Not only in the clipping stages but also in the op-amps and transistors for amplification. Shaping its dynamic and responsive… Read more
