A Boss FZ-5 Fuzz. Three fuzz voices on a mode knob, modeled with Boss's COSM technology on the Maestro FZ-1A, the Fuzz Face and the Octavia, with fuzz, level and a boost that pushes any of them harder. Mono 1/4 inch in and out, buffered bypass, 60 mA on a 9V battery or a PSA adapter.

Three fuzzes in one box, each a different decade: the FZ-1A is the buzzing 1965 sound, the Fuzz Face is the smoother late-'60s one that cleans up with the guitar volume, and the Octavia adds the upper octave. The boost is the fourth control and it turns any of them from vintage to violent.

New from Boss. Comes with a 9V battery; the PSA adapter is sold separately.
