Hello all. I was wondering if someone can shed some light on "master tapes".
For instance, when Pink Floyd was in the studio in 1978/79 working on The Wall what all was produced? In my mind all the EQ etc is imprinted at the time of recording and what you end up with in a master of the complete album. Or do they have tape of all the tracks without any processing? Do they even have the master tape, and if so, is it still in good condition? I'm just trying to get my head around how we go from a 1979 UK 1st pressing from the original tape to the pressings coming out today.

Thanks!
