EARTHQUAKER DEVICES Sunn O))) Life Pedal V3

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.
