I'm just looking to switch between red/green channel live, and 70 dollars is too damn much. I picked up a Triple XXX switch on ebay for 20 bucks, but unfortunately the buttons aren't doing anything for me. I was under the impression that any of the 7 pin switches would probably work?
Dunno' about the one you bought. I use one from a Peavey Classic with a 5150 and it works fine so I suppose you could try a Peavey footswitch. Looking up "peavey footswitch" brings me lots of results of it for about the price you paid for the Triple XXX one on Ebay.
The trouble is that the 7 pin switches for the 5150 II/some other Peavey amps are less common/usually more expensive. Can anyone confirm which ones work with the 5150 II?
