The Vahlbruch KALUNA is a completely new overdrive/distortion pedal, whose 100% analog circuitry is based on a 250-volt ECC83/12AX7 double triode tube. The high voltage required for this type of tube circuitry is generated independently inside the pedal from the standard 9V power supply and is responsible for the "right" overtone content, the certain overdrive transparency, the percussive attack behavior and the typically complex compression that we all know and love from overdriven tube amplifiers.
