Description

Edit description

Sunn O))) and EarthQuaker Devices are pleased to bring you the most compact, pedalboard-friendly version of the Life Pedal distortion circuit to date – the Sunn O))) HalfLife Octave Distortion + Booster. Half the size, just as heavy.

Controls:

Octave (O): This blends in the analog octave as you turn it clockwise.
Filter (F): This is a low pass filter with a frequency response from around 500 Hz to 30 kHz. Turn counterclockwise for more high-end, clockwise for less.
Distortion (D): Turn clockwise for more distortion, counterclockwise for less. This provides about +60dB of gain.
Magnitude (MAG): This is the output volume for the booster. Clockwise to blow up your amp, counterclockwise if you’re a baby. Unity is somewhere right around noon on the dial.

Clipping Switch (CLIP):

OpAmp: No diodes to allow for full, grinding Op Amp 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.
Amplitude (AMP): Output volume for the octave distortion side. Clockwise for more hearing loss, counterclockwise for a healthy life in old age.
Magnitude Footswitch: Boost Activator
Amplitude Footswitch: Octave Distortion Activator
Octave EXP Jack: Connect any expression pedal to this input to control the analog octave blend.
