Tone Control for Distortion, Overdrive and Fuzz Pedals

Have you heard about Big Muff Tone Control. It's a very simple, but also very effective tone control circuit, which is an important part of the Electro-Harmonix Big Muff pedals. It is also used in many other stomp-boxes, including DIY constructions.

This circuit can have a great impact on a tone of distortion, overdrive or fuzz stomp-boxes. Important thing about it, is that this tone control is affecting the pedal signal even when the potentiometer knob is at 12 o'clock.

Here, I would like to present my modification of Big Muff Tone Control. I only have changed the values of  parts - to reach different frequency response. (If you want typical BMTC, search online for it - there are a lot of good sources.)

What's the difference between my tone control and the Big Muff Tone Control? BMTC makes the tone more thick and heavy. My version also can add a little bit of thickness, but it's much more crisp and distinct than BMTC.

As you can see, it's quite simple.
