From the post

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.
