I just finished a Boss CE-2 clone using this layout, http://tonepad.com/getFileInfo.asp?id=101. It works to some degree, but there are some bugs I'm still trying to work out of it. The two things that aren't quite working right, is that when it's switched off there is a clicking noise that sounds like it's going at the rate of oscillation, but I'm not sure how to correct that. The other problem is that when the effect is switched on there is a large loss in volume. I'm not sure if just changing a resistor value (R26 on the schematic) would fix this problem or not. Thanks for your help.
