Great information all!! Thank you all so much. All points to what I thought was the base of my problem... the audiophile not having an instrument In/Out. I got confused because it DOES have inputs and outputs, just not the right kind. Something I should have known.
Now... your help has reinforced my thoughts of upgrading my Sound Card, which after a big computer upgrade (to 4core 64) and software upgrade (X2), is now the weakest link. I'd really like to get a sound card that plays nicely with my current set up and also, obviously, has at least 1 instrument line in.
So I'm off to search and research threads about Sound Cards!
Thanks to all who responded. This is truly a wonderful, civilized and caring community.
Best,
Rob
EDIT: Hmmm after looking up audio interfaces, I don't see a lot of sound cards with Instrument inputs.... Now i'm thinking that I'd need a preamp anyway... so now I'm back to preamps
