What I mean is, is the adjustment about the same or are they entirely different beasts? I'm not much of a guitarist but it seems to me that adding strings could make things a lot harder considering how chord oriented guitar is vs bass being primarily one note at a time. It's just a guess but I'd imagine that being proficient on 7 and 8 string guitars would take a bit more work that moving up the string count on a bass. Anyone have any first hand experience they'd like to share? I'd love to get a 7 or 8 but I probably won't right now, haha.
