New Earthquaker Devices Sunn O))) Life Pedal V3 Limited Edition Sapphire Blue

From EarthQuaker Devices:

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.

What Is It?
Sunn O))) Life Pedal is a distortion with a blendable analog octave up and a booster combined in one compact package. The "Amplitude" side is faithfully modeled after the classic "White Face" distortion unit, using modern, reliable components to last a lifetime. The only modifications made to the original circuit are in the clipping section. The traditional circuit uses a single pair of silicon diodes for a tight, compressed crunch. The Sunn O))) Life Pedal introduces two additional clipping options: no diodes for full, grinding OpAmp assault at maximum volume; two silicon diodes and one LED in an asymmetrical clipping configuration for a slightly compressed and smooth crunch similar to a valve amplifier; and the stock double silicon diode configuration for that classic tone you know and love.

The Octave in the Sunn O))) Life Pedal is an all-discrete, analog full-wave rectifier based on a classic vintage design. Located at the input of the circuit, the Octave control slowly blends in the octave effect as you turn it clockwise. This feature can also be used via expression control allowing for wild, hands-free octave swells mid-riff. Because this is an analog octave effect, it is monophonic and works best playing single notes above the twelfth fret while using the neck pickup. The "Magnitude" section is a simple all-discrete MOSFET booster designed to blast your preamp tubes and drive them wild. It is a 100% clean, high impedance booster that adds very little color to your tone.

The signal path goes Octave > Distortion > Boost. The octave distortion and booster can be used independently with their own respective footswitches.

Controls
Octave: 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: 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.
Clipping Switch: OpAmp (no diodes), Asymm (two silicon diodes and one LED, asymmetrical), Symm (stock double silicon diode).
Magnitude: Output volume for the booster. 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; the distortion ("Amplitude") must be active.
Octave EXP: Connect any expression pedal to this input to control the analog octave blend.

Flexi-Switch Technology
This device features Flexi-Switch Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching. Since the switching is relay based, it requires power to pass signal.

Power
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. DO NOT RUN AT HIGHER VOLTAGES!
