This pedal is an Octave Fuzz that was designed for bassists. The original sound can be mixed with the fuzz sound, so there is no decline in tone. The fuzz effect delivers an outrageous sound, including the upper octaves. This octave sound can be switched on and off by the Fit switch. The wide range of tone control allows for a variety of possible sounds. This pedal can of course also be enjoyed and employed as an extreme fuzz effect by guitarists, as well as bassists.
