I just got the Delta 44 for christmas, and acid music studio 7. I'm going to be using it for recording my bass and my roommates guitar. We just aren't quite sure how we should hook it up. See we don't have a pre-amp, but we have:
an bass, 3 guitars, a bass big muff pi, a digitech bp80, a boss gt6, a fender rumble 15 bass amp, and a mesa boogie dc5 amp.

Do we need a pre-amp to record or will our amps work? and in what order should we hook everything up? Any suggestions would be great.
