Guyatone MOm5 Mighty Micro Octaver Effect Pedal. This rare and discontinued pedal is a peice of guyatone history. Featuring One- and Two Octaves down voices along with Dry Blend, the MOm5 also has a 3-way Filter switch that selects between a fuzzy, square wave octave tone, a milder sine wave, and a deep organ tone aswell as a signal input control to boost or cut the signal before it gets into the circuit.
