So I've got two tube amp rigs which will both have 4x12's underneath them. Naturally, I thought it'd be a ton of fun to run them both at once for when it's just me playing by myself. If anything, I figure I'll get more experience dialing in two tones that work together. I also wouldn't mind having one set up for cleans as they're both single channel amps. So the two main options I've been looking at are: Loop-Master ABY ABY Box Pedals - Loop-Master Pedals - - ABY Pedal (LED Version) Radial Bones ABY Radial Bones Twin City A-B-Y Amp Switcher | Sweetwater.com Now, my biggest concern is loss of signal. I like to be lazy if possible so when run through the pedal on just a single rig I want it to sound as if the pedal isn't there. Same goes for when both are engaged. I don't want any loss in volume or tone suck. I have some Loop-Master pedals here and while they are great they could use a rubber shoe and some extra weight, but it's not a big deal considering they are incredibly well priced for what you get. The Radial Bones looks like it has a good build but I've got no experience with them. Does anyone have any input for these?
