One-Knobber Project

I haven't made a detailed project in a while, so for Fuzz Friday here's the One-Knobber. It's based on the old Dr. Tony Balls stripboard layout that covered the ColorSound One-Knob, D*A*M Meathead and Dark Meathead, and a one-knob adaptation of the '66 Vox ToneBender, and I've added the Ritual fuzz by Black Arts Toneworks.

    1. You'd replace R6 with a 1 or 2k pot and move C4 across lug 2 and 1 (negative side of the cap going to lug one which is going to ground). Honestly, you're probably better off building something like the Jack DeVille Vintage 2-knob Fuzz where the layout already has the fuzz control.

  7. Gathered on the layout of the Ritual Fuzz, but it was not working. Later, I checked the layout with the scheme and found that the pinout is 2n2222 inverse, they need to be rotated 180 degrees. Good luck in the assembly :)

  9. Hi everyone, I built the pedal with colorsound components. When the volume pot reaches about halfway, however, the sound becomes completely clean and there is no longer any distortion.
    Do you have any idea why?
    Thank you all.
