Your statement is conflicted. How can it both be the accurate tone and have overlays. BTW, pieces of of the original guitar track will be removed and overlayed onto other tracks. Only a perfect separate will guarantee full accuracy and that is not possible. So, only the original, isolated recorded track is fully accurate. And if you listen to it on utube, it is further degraded, but that is an other discussion.
Any track from separator software is not exactly what was recorded and will therefore not fully represent the original recording. By the way, this is not debatable. It is a fact.
My experience with RipX is the guitar tone is there without subtraction of overlays but with addition of overlays. Anyway, it's close enough to study tone without having to stand next to the Artist in a studio alongside his equipment. No one is capable of getting the exact tone even the Artist on the same day in the same studio.
The OP asked for "beginner steps". And I am sure we have offered him steps to learn beyond his current predicament.
