I bought a Y cable splitter because before I would simply plug in a single guitar cable from my behringer xenyx 802 into my pod xt live. There is a "L" and an "R" on the MAIN OUT for the xenyx 802 and I would just plug into the left channel and then record. Since I was only technically plugged into one channel I'd assume I was recording in mono. Since I got my Y Splitter I am now plugged into both "L" and "R" on the main out yet when I lay tracks down I don't know if I really hear much of a difference. My real question is whether or not I really needed a Y Splitter cable thoughts? edit: also I hope I posted this in the correct forum!
