Poly-pig

Project overview

This circuit delivers everything from subtle overdrive to heavy distortion. Inspired by Pigtronix Poly Saturators, this versatile and multifaceted board was made for any type of music and player.

Introduction

The Poly Pig is a dirty, chunky, snarly creature that can be tamed to become the most docile and fluffy mate. Get everything from face-melting distortion to mild overdrive with hi-fi definition and clarity.

Its unique JRC4558D-powered EQ circuits will allow you to have all the accuracy you need to shape your frequencies, and the A-Class A, JFET front end assures you a wide range of warm, tube-flavored gain.

This pedal is perfect for detuning and grinding; we warn you: if you piss off the pig, things will get serious! With high gain settings, it squeals and growls like a wild beast.

When the gain is backed off, the Poly Pig emits a bluesy and gritty soft grumble. It becomes wholly docile and cleans up nicely by backing off the guitar volume, making it highly versatile and usable.

This compact pedal plays well with guitar, bass, and synth and sounds great while doing it. It’s your choice: domesticate the beast or explore its wildest side!
