Apocalypse Audio Dirty Boots Version 5

Continuing with the layouts I made that day. Here's the fifth version of the dirty boots. It's a germanium overdrive based on the first version, there's an additional pre-gain pot that controls ho much signal is entering the effect.

  2. I built this, but used 22nF caps instead of 2nF caps, since I found a V5.1 schematic with 20nF caps in front of each transistor. However, the sound was much more like a distortion than an overdrive. Putting a 2.2nF cap in series at the input did result in a tighter, cleaner sound in OD territory, so maybe 2nF is not too small for the coupling caps after all. The layout works, in any case.

    For transistors, I used a few different 2n586's with Hfe's around 60. Silicon 2n3904 and 2n5087 transistors also worked well for Q1.
