From the vendor

Project overview:

Inspired by the now-discontinued distortion pedal Boss DF-2. This circuit reminds us of the classic BOSS DS1 in its Distortion side, but it’s the feedback and overtone section that really makes it stand out making this circuit capable of endless sustain. For this pedal, we included an additional momentary footswitch to enable the feedback mode.

Introduction

Chief Feedstortion is a distortion pedal with the added option of holding down the footswitch for endless sustain – in overtone harmonic form of single notes, even at low volumes. The set of knobs will allow you to craft the type of distortion you want, adding lots of tonal versatility. The level, tone, and distortion knobs will let you craft the distortion, whereas the overtone knob allows you to adjust the feedback.

You are the chief in charge of this feedback station. Enjoy every minute while maintaining the situation under control – tame your feedback or let it go wild; after all, you are the boss.

Just try not to get an eviction notice from your neighbors!
