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.

Black Arts Toneworks Black Forest

This is Black Arts' take on the Colorsound Overdriver. There are a few component value changes and 6 different caps on a 2 pole, 6 position rotary switch at the input. It's got a wide range of tones, and goes from boost to overdrive to fuzz. It's laid out for board mounted pots and would fit in a 1590B if it weren't for the rotary. If you wanted to skip the rotary and just use one input cap, just populate the capacitor you want and jumper its corresponding pad to the SwA pad.


  1. Can BC109C be replaced with BC109B?

    1. You could, though the B version is lower gain than the C. You're better off substituting the BC109C with BC549C or BC550C.

    2. Thanks! I found BC550C in my local storage.

    3. I've tried replacing BC109C with BC550C. Is it normal, that sound is fuzzy only when gain pot is max?
