I've got an idea! (It's not original - others have suggested it before, but it never seemed to take off.) We throw around little buzzwords about tone but never really explain the terms. As an example, describe "growl" to a Martian. Or "punch". Or "fart" (as in Jack Bruce's Blind Faith era tone). Why don't we start a thread giving examples of various tone concepts, and in which questions about how to uniformly describe something can be asked? I'll start out - how would you describe John Paul Jones' tone on Led Zep II, particularly on the "Thank You" and "Ramble On" tracks?
