I got a new power amp today and am going to start looking for a preamp. Anyway, i tried the amp out using my Korg FX unit, and figured out that in order to run both channels, I need to have input going to both the channels. So my question, do you guys know anywhere that sells a short (i would like around 6-8 inches) Y cable? I would like to avoid making my own, as I dont know how (also too lazy). I guess i will make my own if it comes down to it though. Another question too, is this a common thing, or do some power amps drive both channels off one input?
