I have a RIC and a stereo cord. Currently playing in a 3 singer sometimes no drum type setting. I liked the sound of my bass coming out of one amp and some effect, chorus or whatever, coming out of the other amp. Rather than hauling 2 heads and 2 cabs, i thought of buying a 2 channel head. ANY SUGGESTIONS? 500 watts at 4ohms, 250 at 8ohms is fine. Has anyone ever done this?
