The PC-2A is a true vintage studio compressor in a stompbox. The tube circuitry delivers stacks of head-room and low noise floor for outstanding dynamics: preserving the attack characteristics while creating musical and natural compression. The PC-2A wraps your signal in velvet: enhancing your tone without stamping a solid-state signature on it. Useful in live situations for adding ‘punch’ or fattening up thin single coil pickups and indispensible when recording to prevent the nasty transient distortion artifacts that modern digital devices produce if overloaded. Acoustic players will also appreciate the smoothness and sustain the PC-2A adds to amplified acoustics, especially those fitted with piezo pickups. Video demo of the Effectrode PC-2A Compressor.
