The Two Notes Le Crunch Pedal is a guitar preamp with A and B mode - or Fusion mode. Fusion mode utilises both channels. You can do this in Cold mode (in parallel) or Hot (cascading A onto B). Le Crunch is derivative of the high gain British amplifiers that have defined the sound of rock n roll since the 1960’s. Le Crunch is part of Two Notes Le Preamp series of versatile guitar and bass preamps / amp simulators in stomp box format.
