The Catalinbread Fuzzrite Germanium pedal modifies the classic Mosrite Fuzzrite silicon fomular with a germanium construction and includes two NOS PNP germanium semiconductors with a polarity inverter IC so it plays well with all forms of power. Unlike the original, Catalinbread has added a toggle switch to shift into modern mode, significantly beefing up the low-end content to suit more contemporary rigs.
