MXR M287 Sub Octave Bass Fuzz

General

• Bypass: True Hardwire
• Controls:
• Dry circuit:
• Dry: controls volume of unaffected dry signal
• Mid+ Level: sets amount of dry signal’s midrange boost
• Fuzz circuit:
• Gain: controls intensity of fuzz signal
• Fuzz: controls volume of fuzz signal
• Bass: cuts/boosts fuzz signal’s low end frequencies
• Treble: cuts/boosts fuzz signal’s high end frequencies
• Fuzz switch: toggles between two fuzz modes
• Octave circuit:
• SubOctave: controls volume of sub octave signal
• Footswtiches: Bypass, Octave
