Différences avec la FZ-3

Citation : Since the FZ-3 was discontinued 1999 there hasn't been a Fuzz pedal in the Boss line up. This has been rectified by the 2007 release FZ-5 Fuzz. The FZ-5 is however very different from its predecessor. Whereas the FZ-3 didn't have any integrated circuits, the FZ-5 is using COSM modelling which means most of the signal processing occurs within an integrated circuit.

The FZ-5 has a mode knob with 3 different settings: F, M and O. These 3 settings correspond to COSM emulations of the Dallas Arbiter Fuzzface, Maestro FZ-1A and Roger Mayer Octavia respectively. It does not emulate the FZ-2 or FZ-3 so if you're looking for the fuzz tone these produced you will need to look into the used pedal market.
