Great sounding from those stock Epiphone 57 stock pickups: middle position is just what i was looking for and was always missing in humbucking guitars, pretty similar to the Gretsch's Filtertron pickups. Grover tuners do the job, but i miss some real locking tuners for all those string bends i do in gigs and tunings to be made in the middle of the concert. Tune-o-matic bridge ain't nothing special, as well as the Stopbar... Anyway, swapped mine for a Bigsby B70 Tremolo and StewMac Roller Bridge, so the stock one is irrelevant. Never had a single problem with its electronics, and mine is from Korea, made in october 2005. Great guitar overall, and i must say it is on a professional level along with all my other guitars, great sounding and use. 9.5/10 for the tuners.
