Delivers Distinct Fuzz Tones

The FZ-5 Pedal is built for the modern player, with state-of-the-art technology and a road-worthy construction to ensure it can survive the life of today’s guitarists. Although the FZ-5 is a modern pedal, its fuzz is purely retro, taking inspiration from famous fuzz pedals of the 60s/70s and recreating them using Boss’ COSM technology. Players are given access to three distinct fuzz tones, with the addition of a boost control to deliver extra levels of aggression. Selecting the F mode will deliver the fat fuzz tones found on psychedelic music of the late 60s, while the M mode provides a fuzz with a prominent boost in the high-end. The O mode delivers a special octave fuzz, delivering the classic fuzz character with an overlaid sound an octave higher.
