I have an Aphex 204 that I've been loving, and want to try an experiment. There are lots of useable settings, and I am tired of using only one at a time. What I want to do is use both channels and have a footswitch to select them. I run the 204 before the head, so the bass goes in the input, then I take the output to the front of the 800 Pro head. What I want to do is use an A/B switch before the Aphex to choose the channel that gets my bass's signal, then have each output going to the front of my amp. Essentially what I need is some sort of cable sum (2 1/4" into 1 1/4" adapter) to go between the Aphex outputs and my 800 Pro's inputs. Does anybody know where I can find such a beast? Also, if anybody has done this before, or has any other advice on how I may do this, help is certainly welcome. Thanks in advance.
