Dave Koltai, Pigtronix founder, came to our shop in CT when he first decided to make effects pedals, and showed us his original Envelope Phaser. We gave him our opinion and some hints and I think we were his first dealer. We are the only dealer who still has those original EP-1 pedals, as he showed us how to calibrate them and get them working well.

Ridiculously FAT, Funky Tone for Guitar, Bass, Keys, Turntables, Laptops and Studios.

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 "EF trigger" input allows an 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.

We are testing them and calibrating them before we ship them, this takes a while, maybe up to a week if needed.

Uses included (US 120vAC) 12vAC power supply.
We can change to a Euro or UK power supply for $20.
