Project overview

The Clean Blend Master is a multi-task pedal that allows you to blend your instrument’s unprocessed “clean” signal with any pedal you use. It also eliminates any unwanted phase cancellation in your chain, prevents signal loss, and adds that additional gain stage when needed. This is a must for any effects pedal setup.

Introduction

Have you ever wanted to add a clean blend to your favorite dirt pedal? If you love thick and saturated fuzzes and distortions, for sure, you have felt your bass frequencies losing definition and presence, getting lost in the mud of the mix. This is the case with many classic distortion pedals such as The Rat, Muffs, Boss HM2, and most dirty fuzzes.

That’s why we created the Clean Blend Master, and stand-alone board that helps you to mix up your dry signal with your dirty tone keeping your lower strings well defined through the mix.

To make this board the most versatile, we added three toggles that make it easier for you to craft your perfect tone.

First, you have an inverting phase stage to match any drive pedal.

At the return of the dirty signal, we added a buffer switch to give extra power to your dirty signal.

Last but not least, you have an additional gain stage to slightly boost your overall signal blend.

We developed this tool to make the custom PCB design easier, and now you can experiment and design your own pedal by adding this to your favorite dirty pedal.

And remember, once you have a clear idea of your ideal guitar pedal, you can order custom PCBs for your run of pedals right here.
