The UMI Buzztone "Expands" upon the typical fuzz pedal, allowing for two different stages of overdrive. The first stage, which cannot be bypassed, is essentially a volume boost. Once the pedal is engaged the contour controls the tone, and the buzz controls the amount of fuzz. This simple circuit with (2) germanium transistors is extremely unique, and really sounds unlike any other fuzz produced at the time, so whether you fancy yourself a fuzz fanatic or a collector of special musical tools, this is definitely something worth owning.Condition:
