Jim Dunlop MXR Blue Box Octave Guitar Pedal

The Blue Box Octave Fuzz drops your guitar signal two octaves down and combines it with gnarly fuzz for huge subterranean tones.

This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick, Iso-Brick, and Mini Iso-Brick power supplies (not included).

Directions:

1. Run a cable from your guitar to the Blue Box’s INPUT jack and run another cable from the Blue Box’s OUTPUT jack to your amplifier.
2. Turn the OUTPUT knob clockwise to BOOST the effect’s overall volume.
3. Rotate the OUTPUT knob to increase overall volume of effect or counterclockwise to decrease it.
4. Rotate BLEND knob clockwise to increase amount of sub-octave fuzz or counterclockwise to decrease it.
