Edit 2015-06-12. Updated the layout slightly to match the latest schematic. Anode of D7 moved down two rows.
Here is another very nice compressor / overdrive. This one is a brand new creation from Sam Hay, the inventor of the Cherub Chorus that I posted a layout for earlier. Read more about it in the original thread here.
For schotty diode I used a 1N5817 in my build with good results.
Here is an old circuit from Elektor, a dirty compressor and distortion in one. I was surprised that this one actually sounds really nice. The compression goes from fairly clean and subtle to very compressed and dirty. The distortion isn't bad either. :)
I didn't have a BF256C, so I tried both a 2N5457 and a BF245B insted with good results. Just keep in mind the pinout.
All the layouts are Verified unless noted.
