One of the very first electronics projects I can remember doing was when I took a cassette player and somehow managed to find the input for the amplifier section in it. Now whether it would be cheap for you, if you have to ask then that suggests to me that things might not go as planned. I didn't look at what other layouts you may have posted, but if it's a trend, you might wanna practice some simple layouts before diving in the deep end :) If you need help fixing it, just say so - I could make the schematic more readable as well.ДЄn even quicker look at the overdrive pedal that you link to, seems to have very similar layout 'qualities'.

Just went down with a fever and a blinding headache, so I might have missed other stuff. Not sure where you connect ground from the power supply either. Normally I'd say 'back to square one' to a layout like this - 8 unconnected traces, more than 10 acid traps, awkward component orientation and just as awkward 'pads' and traces not commanded by the schematic, topped of with this very strange build-up of rectangles (was it meant to be a pseudo copper fill?). Took a quick look at your board and must conclude that you dislike board layout as much as digital electronics )

If anyone finds any problems then let me know and I'll see what I can't do to fix it.' 'Anyhow the one I am including here looks pretty good to me.
