From the post
Updated 31st January 2014: A lot of people have mentioned that the trimmers in this aren't as important as finding the correct transistors, so I'd recommend building this version which omits the trimmers entirely and puts the fixed resistors back.
Make sure you use sockets for the transistors and prepare yourself to audition plenty! :o)
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
