Up for sale, a Polytone Multivoicer fuzz guitar effects pedal in excellent condition and in perfect working order. This extremely robustly built and extremely rare fuzz has a natural octave up effect most prominent in higher registers, yet without the ring mod artifacts one expects with most octave fuzz boxes. This pedal has a rich growl that chords well, with more clarity than many fuzz circuits, and it's a chunky powerful sound that works well with a variety of guitars and amps.
