Pigtronix EP-1 Envelope Phaser features an incredibly fat and vocal, touch sensitive envelope phaser as well as a deep and chewy, univibe style rotary phaser with enough controls to dial in your own special sauce.

The EP-1 is an expressive, flexible, dynamic effect with a warm analog personality, versatile tone palette and a stage friendly interface.

	EP-1’s trigger input allows your instrument’s sound to be phase modulated by an external audio source, such as a drum machine or laptop beat. This side chain input can even be used as an FX loop for maintaining accurate envelope response when using other effects in line before the EP-1. The Envelope Phaser also features footswitchable phase inversion, expression pedal speed control for mind bending rotary speaker effects and can even be used as a clean analog fat booster. Destined to be the modulation effect of choice for many guitarists and bass players looking or that elusive "liquid tone" the EP-1 will also find itself at home in the hands of scratch DJs, laptop musicians and recording engineers.
