The MXR Bass Octave Deluxe is a dual voice octave pedal that gives bass players two unique octave tones (both one octave below). Use the Dry knob to combine as much or as little of your original bass tone with the affected signal.
The Modified O.D. is a new twist on a classic OD circuit. The tweaks offer added versatility and performance. A Bump switch engages an alternate voice for low and mid-range boost. True bypass switching makes it completely out of your signal path when not engaged.
