Build Your Own Clone Message Board

Hello,

Could I get a little help? I'm new to designing my own pedals (obviously), and not super familiar with convenient ways to use the switches.

I'd like to build this pedal. I'm aiming for a universal pedal that has:

Amp Channel Switch
Amp Effects Loop Switch
Guitar Pedal Loop - front of amp, always on when amp is on Dirty Channel.
Loop1 - Amp Effects Loop only on Dirty Channel
Loop2 - Amp Effects Loop only on Clean Channel

I was hoping you pedal experts could take a look at my crayon drawing and tell me if it would work. I assume I need to isolate the jacks from the chassis so I don't get ground hum.

Is there a better way to do this? I can't find a 5pdt footswitch, and I'd rather not incorporate a relay if I don't have to.

Thanks
