Tone City Fuxx Fuzz Octave Fuzz with toggle option. Mighty Mini! Brings out that famous Ocatve Fuzz response w/toggle option. Extremely well built and all Mini's are not the same ! it can combine a mix of Fuzz, Distortion and an upper Octave (which you can switch off and on by front face toggle.) This is a little beast! All Tone City pedals are True Bypass and require a regular 9v Power Supply for operation as there's no battery slot
