The MXR Blue Box Octave Fuzz guitar pedal drops your guitar signal down two octaves and combines it with gnarly fuzz for fat, low-frequency tones. You can hear this effect heard on Jimmy Page's "Fool in the Rain" solo.

The Blend knob on this MXR pedal lets you control how much of the fuzz tone is mixed with the two octaves down signal. Not for the shy guitarists, the Blue Box Fuzz offers a unique and distinctive sound.

CONTROLS

• OUTPUT: controls the overall volume of the effect
  
• BLEND: controls mix or wet and dry signals
  
• FOOTSWITCH: toggles effect on/bypass (red LED indicates on)
  

The Blue Box Octave Fuzz MXR 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).
