Bearfoot Golden Candiru Germanium Fuzz Bearfoot has updated its popular Candiru Fuzz to the Golden Candiru Fuzz! Our new Golden Candiru Fuzz, which adds a 5th knob for greater versatility like the original Candiru, is germanium rather than silicon-based. The Golden Candiru puts the inner trimpot of the Candy Apple Fuzz on the outside of the pedal in the form of the Gate knob.
