Hi Pete, thanks for the schematics - I've been working through the bends you've posted here and a few others I've found along the way - this is going to be a nice piece I hope. I have not been able to figure out the FX patching yet though - is there any chance you could shed any more light on that? I've cut the trace where indicated and tried "joining the dots" of the two unlabelled connections shown on your schematic, (orange on the left, blue on the bottom right) but so far nothing… Any advice would be great.
Also, as a heads up for others - I thought I had fried my one for a while, but it turns out I had blown the resistor in clear plastic casing next to where -v comes in to the board (top left on your schematic). It seems this resistor might be easy to blow - replacing (or bypassing) it restored life to my 'phone. Thought maybe others might find this helpful.
