Prepare for seismic low-end devastation with the Sub Octave Bass Fuzz, a sonic weapon that combines earth-shaking fuzz with thunderous sub-octave growl. MXR’s engineers have crafted this subterranean monster by merging the acclaimed Growl section from their Bass Octave Deluxe with a long-forgotten fuzz circuit, creating an instrument capable of producing truly colossal bass tones.
The pedal’s three separate output level controls for fuzz, sub octave, and dry signals give you complete control over your tonal recipe, allowing you to blend subterranean frequencies without losing your instrument’s natural character. This flexibility means you can dial in everything from subtle low-end enhancement to full-blown sonic chaos.
Additional versatility comes through the fuzz section’s comprehensive tone controls and two distinct switchable voices—choose between warm and compressed tones or bright and aggressive attack. The Mid Level control adds another dimension, letting you punch through the mix by boosting your dry signal’s midrange presence, ensuring your bass cuts through even the densest arrangements.
