Help! Problem building a looper/bypass switch

[ozzy]

If anyone can help me with drawings, what the best parts are to use etc. that would be great.

basically what i am biulding is a pedal with three switches, in input from a guitar, an output to an map, an output to a channel changer on an amp, an a send an return fo an FX loop.

Switch 1 goes to a 1/4 inch jack which controls the boost/channel change on my amp, it's an on/off switch and that bits pretty striaght forward!

Switch 2 controls the FX loop and adds in or removes it, or puts it inbetween the guitar and the amp, again this is pretty straight forward but I want to avoid any nasty clunks or ground loops.

Switch 3 is the bastard, this switch needs to reverse what ever the other two switches are doing, so I can turn switch 1 and 2 on at once or one switch on and one switch off....

i hope this is clear enough, any help would be much appreciated.

thanks, Ozzy.

er, well I think you need to elaborate a bit more in order to get a response. But, there are already a lot of threads that discuss the whole switch pop issue, take the time to read through a few and be willing to experiement.
