I've dealt with lots of folks mentioned: Ron Ruggiero (20 yrs. ago), Nick Bucci, the DiPinto shop, and of course Bass Specialties but not for a setup. They're all great. Nick Bucci and Chris DiPinto are excellent luthiers, and I would completely trust them with any setup or repair. (I saw Chris DiPinto's band the other night, and he plays a mean lead guitar too. Very cool guy.) I usually take my basses including G&L's to Bluebond on 4th between South and Lombard. I really like the folks there and they do good work, but they take a long time these days. Next time I might go to DiPinto. When I had a DiPinto bass, they would set it up for free, and they did excellent work.
