Black Arts Toneworks Black Forest

A modern upgrade on the Colorsound Overdriver.  I have included a 6 position 2 pole rotary switch and you can do it one of two ways.  Use the cap daughterboard I have shown in the layout (which will only actually uses one of the poles), or if you prefer you can just solder the caps straight to the switch like this:

Input > Sw A
8n2 between lugs 1 and 7
10n between lugs 2 and 8
22n between lugs 3and 9
47n between lugs 4 and 10
220n between lugs 5 and 11
470n between lugs 6 and 12
Sw B > out to Q1 base on board

If you do solder straight to the switch then I'd recommend putting a 1M resistor between the input wire and ground in a convenient place to avoid those switch pops.

Info about the original:

Black Arts Toneworks unleashes their latest pedal, the Black Forest overdrive. Based on the legendary Colorsound Overdriver, the Black Forest provides that classic tone in spadeswith a difference. Not only is the classic Overdriver tone there but the Black Arts Toneworks Black Forest adds more grit and gain as well as a bit fatter tone than the original while at the same time decreasing the noise floor to astounding quietness. When the gain is maxed out, the sound is very fat with harmonic-laden overtones and a classic sound that no guitarist can deny. In addition to this, the Black Forest also features more tonal control with the addition of a six way Depth control. This allows the user to cycle through six different capacitor configurations that alter the voice and gain structure of the unit offering an array of sounds not available in the original circuit. The additional gain on tap allows the Black Arts Toneworks Black Forest to achieve anything from a gritty boost to a classic overdrive to a vintage fuzz tone and will keep the inspiration coming for even the most seasoned players.
