• SUB OCTAVE Knob: Controls the output level of the sub-octave signal. Turn clockwise for more sub-octave.
• OCTAVE Switch: Toggles the fuzz signal into an electrifying octave-up mode when engaged.
• SERIES Switch: Selects the routing of the sub-octave signal. In Series mode, the sub-octave signal runs directly into the fuzz circuit for subterranean saturation. In Parallel mode, the sub-octave signal runs alongside the fuzz for a split-channel effect.

4. Sound Exploration & Usage Tips

The MXR Sub Machine Fuzz offers a wide tonal palette. Experiment with the controls to discover your preferred sounds:

• Vintage Fuzz: Start with the SUB OCTAVE knob fully counter-clockwise (off) and adjust FUZZ and TONE to dial in classic fuzz tones. Engage the OCTAVE switch for searing octave-up fuzz.
• Subterranean Saturation: Engage the SERIES switch and gradually increase the SUB OCTAVE knob. This routes the sub-octave directly into the fuzz, creating a thick, heavy, and saturated sound.
• Split Channel Effect: Disengage the SERIES switch and blend the SUB OCTAVE with your fuzz tone. This creates a distinct, layered sound where the sub-octave retains more clarity alongside the fuzz.
• Sub-Octave Only: Turn the FUZZ knob fully counter-clockwise (off) and adjust the SUB OCTAVE knob for a clean sub-octave effect.
