A special version of the PLASMA Pedal: Created by Gamechanger Audio, Jack White and Third Man Records. The PLASMA product series is a revolutionary approach within the realm of overdrive and distortion, as it is a new and previously unexplored method of achieving signal clipping. Instead of using LED circuits, transistors or vacuum tubes to produce overdrive, PLASMA technology transforms your instrument’s live signal into a series of continuous high-voltage discharges within a xenon-filled tube. In essence – you are playing a bolt of electricity, and the electrical discharges produced by your instrument are instantly converted back into an analog audio signal, producing a quick, responsive, and extremely heavy distortion with TONS of unique character! The PLASMA Coil features a specially designed multi-mode FX section with six types of octave-down and octave-up circuits. Subharmonics are produced by modulating the Xenon tube's Voltage with multiple divisions of the instruments fundamental frequency, resulting in a glitchy, distorted octave-down sound that is somewhere between a ring-mod and a bit-crush effect. Upper harmonics are produced by using a full-wave rectifier and band-pass filter, creating an octa-fuzz type sound with a distinct 2nd harmonic enhancement (which is perceived as an octave-up effect).
