Okay so after a long bout of thinking I was gonna biamp and use an ABY pedal, I've decided frugality is the way to go. I'm gonna stick to my Fender Twin and I just want the ability to switch BETWEEN different pedal loops, not turn them on and off like all the looper pedals I've found do. I envision something like this:

Any idea who could build me something like this for a reasonable price and a fast timeframe? I accidentally impulse bought a Loopmaster looper, and while it was incredibly well-made that dude has a gigantic backlog-- from order to shipment it was like three months!
Thanks to anyone and everyone in advance.
