The Pigtronix EP2 Envelope Phaser guitar effects pedal 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. The Pigtronix EP2 pedal is a complete redesign of Pigtronix" Envelope Phaser concept, built on 6 years of customer feedback from the original. The Pigtronix EP2 effects pedal sports sounds and smart features, in a considerably smaller package. The Pigtronix EP2 guitar pedal makes it easy to dial in monster envelope tones for any instrument or playing style. The envelope in the EP2 kicks it up a notch with a "Staccato" function that is ideal for fast-picking, funk bass and tight rhythm guitar. The Stacatto circuit is 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. The Pigtronix EP2 pedal"s rotary modulation LFO provides adjustable depth and center controls for fine-tuning the frequency range of operation, from subtle swirls to screaming sweeps with a huge range of available speeds. Another crucial addition to this Pigtronix effect pedal is the "LFO smooth" switch, which automatically reduces the resonance setting when the LFO is in use. This performance-friendly function finally lets you switch between corpulent, Mutron-style quack, and deep, swirling Uni-Vibe sounds with a single footswitch stompno knob tweaking necessary on stage. In addition to its unique voice and interactive modulation section, Pigtronix EP2 incorporates additional control options, including expression pedals for both Sweep and Speed, as well as a continuous blend between envelope and LFO modulation sources. The Pigtronix EP2 guitar effects pedal retains crucial features from the EP-1 such as true bypass switching, + or - phase inversion and the signature "trigger" input for manipulating the envelope with an external audio source. EP2 guitar pedal runs on 18-volts for maximum headroom.LFO modulation with speed, depth and center blend combines LFO and envelope signals Envelope travels up or down Side-chain trigger for beat sync Intelligent envelope response Invert switch for + or - phase Compact aluminum chassis True bypass switching Assignable resonance kill switch Pigtronix 18VDC power supply included Expression effect pedal inputs for sweep and speed Circuit design by Howard Davis
