Re: NGD - Ibanez SZ1220
I think both of those SZs are beautiful. I was always fond of that line, though I never owned one.
Is the top a full maple cap or a veneer? The pickup cavities might be the best way to tell as the edges can be deceptive if they did a wrap-around. If it's a veneer, trying to sand it would probably be ill-advised, as it would be really tough to avoid sand-throughs.
