I have found myself with 3 different heads and one cab that I have in my studio. I would like to be able to switch between heads without re-cabling the speaker cable from each head to my "reference" cab. Plugging my bass into the input of each head is not a big deal but having to get behind the amps and run the speaker cable to switch heads is a hassle. I would like to A/B/C different sounds from the heads through the same cab easily. Is there some sort of switching device to facilitate this? I tried searching but came up empty.
