I have a line on a used (2 owner) G-K 700RB-II. I know this is the model I want, but I've never bought a used head. I asked the seller a bunch of questions (which he thouroughly answered). There is no original paperwork (I now manuals are online). The original owner gigged with it but it was always racked and he didn't have it long. The current owner has used it for practice and about 5 gigs in the last year. Never been spilled on, always in rack. Some rack rash but I'm not that concerned with that for a used head. He says it plays beautifully. I'm getting some photos sent to me so bar any major issues I think I'm in. Is there anything else I should ask or be concerned with? Thanks guys. Oh yeah and it's a good price IMO. $400. Do you agree? Gonna be playing it through an Avatar NEO B212 8ohm cab.
