The Diamond Pedals F-Octave Fuzz combines two fuzz variations in one box. We all like fuzz, right? Well what sometimes can top a good fuzz is an octave fuzz. On the F-Octave a toggle switch is responsible for the two modes this pedal offers: a clear analog Octave Up (purple led indication) and a classic silicon-based Fuzz (blue led indication). The Diamond Pedals F-Octave fuzz is a straight forward pedal and does not offer unnecessary controls, you will only need to deal with a fuzz, volume, tone and the mode toggle switch in order to design your sound. The overall sound is organic, juicy and well focused. We like this pedal.
