Sunn O))) Life Pedal®
Octave Distortion + Booster
Sunn O))) and EarthQuaker Devices are pleased to bring you the Sunn O))) Life Pedal V3. The Sunn O))) Life Pedal circuit has been meticulously tweaked from the original to squeeze every last drop of heavy crushing tone available. The octave section has been fine tuned to make it more pronounced without losing the bottom end and we added a third footswitch, utilizing Flexi-Switch Technology®, for the octave to allow an additional method of quick and radical tone shaping. We are excited to have this back in permanent production, it is a true labor of love.
Birth of a Life Pedal
In the writing sessions for Life Metal Stephen & Greg worked extensively shearing their tones toward a broader energy spectrum over high powered saturation and across planes of sonic character, with the ambition to take full advantage of Steve Albini’s (the recording engineer for the album) exacting capture skills.
The results are astounding: there is breadth and luminosity of colour, vast sonic cosmoses, flashes of abstract colour (synthetic and objective) through resulting themes which emerged from the mastered depths of saturation and circuits between the two players and their mountains of gear.
The Sunn O))) Life Pedal is designed to represent the core front end chain used in those sessions, to drive the tubes of the band’s multiple vintage Sunn O))) Model T amplifiers (or take your fancy) into overload ecstasy. This is a 100w tube amp full stack’s holy dream, or its apostate nightmare.
An octave fuzz inspired by the Shin-Ei FY2 & FY6 units leads the circuit into a brutal big box rodent inspired distortion, recreated with the best components, and including a three-way clipping switch (OpAmp, Asymmetric & Symmetric). Second stage is a purely clean boost to further overdrive the preamp tubes of your vintage system into -scaped harmonics, and feedback overtone bliss.
Chasms are cleared, mountains sheared, glaciers calved, novæ birthed. Vintage valve amplifiers recommended. We hope you transcend.
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.
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
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.
- 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.

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.
For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.
For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.
Since the switching is relay based, it requires power to pass signal.
This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
