Earthquaker Devices - Sunn O))) Life Pedal®

Octave: This blends in the analog octave as you turn it clockwise.

Distortion: Turn clockwise for more distortion, counterclockwise for less. This provides about +60dB of gain.

Filter: This is a low pass filter with a frequency response from around 500Hz to 30kHz. Turn counterclockwise for more high-end, clockwise for less.

Amplitude: Output volume for the octave distortion side. Clockwise for more hearing loss, counterclockwise for a healthy life in old age.

Clipping Switch:

• OpAmp: No diodes to allow for full, grinding OpAmp assault at maximum volume.

• Asymm: Utilizes two silicon diodes and one LED in an asymmetrical clipping configuration. This delivers a slightly compressed and smooth crunch, similar to a valve amplifier.

• Symm: This is the stock double silicon diode configuration which provides that classic tone you know and love.

Magnitude: This is the output volume for the booster. Clockwise to blow up your amp, counterclockwise if you are a baby. Unity is somewhere right around noon on the dial.

Amplitude Footswitch: Distortion Activator

Magnitude Footswitch: Boost Activator

Octave Footswitch: Octave Activator. The octave does not work independently. In order to use the octave, the distortion (“Amplitude”) must be active.

Octave EXP: Connect any expression pedal to this input to control the analog octave blend. Before inserting the expression pedal, make sure the pedal is powered off.
