Note: This is a better Pedal if you use the recommended Pot values listed on the right side of the Build doc.
I own the Original & made these Changes in conjunction with MichaelW's build.
Here is a Demo, it's based on a Zendrive with different clipping with Tubescreamer buffering.
Note where he has the Tone & Presence controls, Thats why the pot tapers were changed!
