I want to give a tip-of-the-hat to a very useful open-source/freeware program for creating circuit board layouts. Branislav Stojkovic (AKA Bane or Bancika) who runs the excellent DIY Fever website has just released Version 3 of his excellent DIYLC (Do It Yourself Layout Creator) on Google Code. It's still in beta, but it already is a much better package than version 2, and seems to be quite stable.
Here's an example of a simple circuit, and then the real thing built from it (well, with a couple of changes):
The board, by the way, is a little phase-shift low-frequency oscillator and impedance buffer - very similar to the old tube tremolo circuits, but modified for transistors. It's designed so that you can easily drop it into existing amps to add a tremolo effect. I've been playing around with this on my P1-eX, which was the first amp I ever built. I'll blog about the tremolo board another time, but suffice it to say it works really well.
