I gotcha now. I do have the original multi-track master tapes, but not the equipment.
Anyway, thanks very much for clearing that up. On the original recordings, most of the tracks were panned either left or right to varying degrees after going through the mixer, especially the harmonized back-up vocals and rhythm guitars. Even though I'll be able to clean the sound up & take out the fuzz noise, my end product won't be stereo like the original. Oh well, it's still worth saving.
Thanks again. (And Merry Christmas!)
Well, if you're interested in doing that, keep js's suggestion in mind - it's not uncommon for four- and eight-track decks to show up in yard sales, usually as a result of someone's garage band folding up before they got their big break. You might find one fairly cheap if you keep your eyes peeled. Digitize the masters, remix to your liking, downmix to two channels, and burn, baby, burn ;)
