Earthquaker Devices Sunn O))) V3

Earthquaker Devices Sunn O))) V3 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 Life Pedal introduces two additional clipping options. The first position is no diodes to allow for full, grinding OpAmp assault at maximum volume. The second position utilizes two silicon diodes and one LED in an asymmetrical clipping configuration. This delivers a slightly compressed and smooth crunch. The last position is the stock double silicon diode configuration which provides that classic tone you know and love.

The Octave in the Sunn O))) Pedal is an all-discrete, analog full-wave rectifier base on a classic vintage design. Located at the input of the circuit, the Octave control slowly blends. This feature can also be used via expression control. 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. Playing chords with the analog octave will sound clanging and chaotic. Using the bridge pickup and playing below the twelfth fret will produce a very subtle octave effect.

The Magnitude section of the pedal is a simple all-discrete MOSFET booster designed to blast your preamp tubes and drive them wild. It is a 100% clean, no-nonsense, 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.
