The Z.Vex Octane 3 is one wild fuzz pedal, with germanium diode and transistor fuzz science used with a ring mod to generate wacky upper octave tones. The Octane 3 results in demented chord voicings and solos that will likely get you fired from your band.
The Z.Vex Machine is an fuzzy, ugly machete-wielding beast built specifically to cut through the mix and help your other distortion pedals sound meaner. No distortion pedal like the Machine exists on earth. Where nothing is happening, this pedal happens.
