From the vendor

Project overview

Inspired by the Heavy Hand of King Tone, the most famous side of the dual overdrive Duellist pedal, isolated and modified with even more features.

The result is a fist of power that acts like five pedals in one and has all the muscle to deliver the exact tone you’re looking for.

Introduction

King Fist has all the features of the side B of the Duallist, the same components, and tone. But it also has extra attributes, including a dedicated potentiometer for the fat setting named “Body” that allows you to dial in the correct amount of added low end to the tone. The addition of an Edge switch position gives you the possibility of adding an edgy, tube’y quality to the tone.

Finally, you can now adjust the clipping section of the pedal. With the flip of a switch, you will get the classic Duellist Side B tone; another flip gives you a more compressed overdriven tone with a growly, gritty quality, great for sustaining lead or riff sounds. Flip one more time to get a silky amp-like tone with rich harmonics and enough volume to overdrive any tube amp.

If you’re after that classic Duellist tone in a compact and board-friendly platform, then this is for you; easy to build and with super versatile controls, King Fist is one of the best drive pedals on the market today – so why settle for anything less than first-class? Use the King Fist, and crush whatever stands in your way.
