The PLASMA RACK is a 1U sized high-end audio effects unit designed for professional and studio use. A significant expansion of the unique High Voltage Distortion concept behind PLASMA Pedal, the PLASMA Rack features an extra large xenon tube that conducts audio signal at voltages of up to 5500 volts. In essence – you are playing a bolt of electricity, and the electric discharges created in the PLASMA tube are instantly converted back into analog audio signal. The result – a quick, responsive, and extremely heavy distortion with tons of unique character and an extremely satisfying noise-gating effect.
