Multiple Cab and Amp Routing

I suppose that I should add...
if putting something like this together (I have all of $20 into it; I used good ¼" jacks...the $4 ones! The bananas were a buck three eighty nine for a dozen) use care in the banana jack spacing so that using the banana plugs which are a mounted pair is possible.

I guess banana plug spacing has an industry standard and they're all uniform. Who knew?

I bet you could wire it with a switching mechanism
