The Pigtronix Envelope Phaser pours on the special sauce to take your tone into outer space. Accentuating and sweeping through the harmonics of any musical source, the motion of this revolutionary phase shifter can be controlled by Envelope, LFO or a blend of both. Envelope Phaser makes it easy to dial in monster envelope tones for any instrument or playing style. This envelope kicks it up a notch with a “Staccato” function that is ideal for fast picking, funk bass and tight rhythm guitar. The Staccato circuit enables an “intelligent envelope” that listens to your playing and quickly discharges the envelope between your notes. This crafty circuit enables incredibly responsive envelope performance, even during rapid fire playing.
