This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Colorsound 3-Knob ToneBender Reissue

I was trolling Google Images the other night looking for schematics and I stumbled across this. I think the only thing this reissue has in common with an original is the enclosure and graphics. It uses a single opamp with soft clipping and a Big Muff-style tone stack. If you use 9mm pots you could probably cram it into a 1590A.

  1. Build this. It works, but volume not even loud. I decided to cut off tonestack. It adds volume and fuzziness to pedal.

  2. I built this today and the same problem happened as the friend above. But, I changed both resistors from 2k2 to 33k and voilà: The tone pot works perfectly! Changing the 100k before 4148's to 220k gives me more fuzz and more loudness! Man, I'm in love with this pedal! Well, verified too!
