Mad Professor Fire Red FuzzThe pedal has a compressed, deep effect to allow equal sustain throughout the fretboard. Tone control was specifically designed to allow tones from mellow fuzz, through slight midcut to thin bright fuzz. The FRF is not another variation of a classic fuzz design but an unique pedal with its own character and extremely versatile Tone control. It is great for recording different layers of Fuzz tones from haunting dark to cutting thin bright. What ever
