I wasn't sure if I should have posted this in the amps or the pedals forum. So I have a pretty straight forward setup right now: A chain of pedals going into the input of a half stack, and a chain of pedals at the effects loop. But like most guitarists, I can't leave well enough alone, so I'm adding a second amp head to my set up. I'm not planing on ever using this for a live setup, just studio. The second amp head is just so I can get different tones. Sharing both heads with the speaker cab seems simple enough. My speaker cab has stereo inputs, so I'll just utilize that. The effects chain for the input seems simple as well. I could either use a pedal that has a stereo output, or buy or build an A/B/Y box. But what are my options for sharing my effects loop pedals between the two amps? Being that this is only for a studio environment, I could just unplug the send/return cables from one amp and plug them into the other. But it would be a lot easier if I had a footswitch option for this instead. I'm really only interested in A/B'ing the amps, if I could Y the effects loop pedals to both heads that would be a nice bonus to experiment with, but I'm really only interested in A/B switching. I just looked through a bunch of switching pedals and didn't really see any specifically for this purpose. I found a few that have a guitar input/output and then two switchable loops. Would it be possible to use this type of pedal? They were kind of pricey though. Does anyone know of anything I could build? I could probably figure something simple out, but I'm always interested to see what other solutions people have cooked up.
