yes that's what i want it to do, ie if the 6.5" jack get's shorted by the effects unit it will short yellow and orange, and if the 6.5 circuit is open it shorts red to green. it does seem to need the burgundy to light blue circuit in tact also to work, and I'm not sure what the capacitor does. The other thing to consider is that the existing pedal creates momuntary shorts, not constand ones.

Hi MP, thankyou very much for your reply. There is nothing on the unconnected pins of the round plugs. I'm not sure about the signal on the different colors of wire, if you explain the right way to test it to tell you what you need I'll come back to you on it. With the pedal open I can short and successfully change between OD2 and clean channels by shorting the yellow and the orange for the clean channel, and the green and red that connect to the od2 switch. I short these by putting a screwdriver touching both wires at the 15 pin plug end. I've tried shorting using just these 4 wires on a 15 pin plug but it doesnt work right, it needs the circuit that links between the switches (burgundy wire), that eventually returns to the 15 pin plug via the light blue wire. I'll help you help me if you explain how to answer other specific questions as I've just decided to start working on electrical projects.

Hi all, I'm a real noob when it comes to electronics so I can't work out how to do this. I have a guitar amp with a 4 channel footswitch running off a 15 pin computer style plug. I have a separate effects processor with an amp control switch. This amp control utilizes a 1/4" mono audio plug to operate and has two settings, open circuit or shorted. I need this to be able to switch between the clean and OD2 channels of the amp, the other one and the amps effects doesnt matter. I'm not good at writing schematics so I've drawn a diagram of how the unit is wired. Is anyone able to tell me how to make a small circuit to get this to work. Thankyou very much in advance, if you have any questions about any of it ask and i'll answer best I can.
