About The Pedal Creators

Everyone can build excellent boutique guitar pedals. Everything we do is to make that experience more accessible and user-friendlier. The Pedal Creators series are the best and easiest to build PCBs ever. Including most resistors and capacitors already soldered on board as SMD components, leaving the key values for you to experiment and craft your own tone. Now you can build a pedal you are proud of in less than an hour without any previous experience. What are you waiting for to become a Pedal Creator?

The Pedal creators – key features:

• Easy to build, no previous experience required. It’s like Lego for musicians.

• Fast assembly finish a pedal in less than an hour. Play your favorite record and enjoy the ride along.

• 100% mistake-proof. Even my grandma can build one while she cooks.

• Build your own boutique pedal. Experiment with different values and make the pedal you always dreamed of.

• Easy to scale. Turn your passion into a money-making machine.

Project overview

Based on one of the most famous and boutique overdrives, the Knight Of tone takes to the limit the possibilities you can get out of this circuit; featuring many possible mods such as external presence control, internal charge pump, and external toggles to select in between the three modes, boost, overdrive, and distortion.

Introduction

This circuit’s origins go back to 1991 when the engineers at Marshall were trying to recreate the classic Bluesbreaker amps’ tone from the ’60s on a pedal format. The result of that was a dual OpAmp based transparent overdrive with the same name as the legendary amp and with the same core design as the one we have here today in the Knight of Tone, as well as on many other boutique overdrives from Analogman’s King of Tone to JHS Morning glory and many others.

On the King Of Tone by Analogman, you got basically two Bluesbreakers circuits with different clipping options that allows you to set the pedal as an overdrive (Clipping on the feedback loop of the OpAmp), Distortion (after the OpAmp and before the tone control, pretty much like a Rat) or as a booster (Without any clipping option engaged)

For this design, we conceived the idea of taking all the things that make this circuit great and take it to the next level. We took many of the great functionalities of the King of tone but making them more user-friendly. For example, we replaced the internal DIP switches that select the diode mode with external DPDT switches, maki
