I just bought a Classic '60's J-bass and I was wondering what the info is on the Pup's. They seem a bit "zingier" than the ones in my '70 J-bass. I was thinking of replacing them with either the Fender CS vintage or Duncan Antiquities. I play almost exclusively "old school"; blues, r'n'b, Motown and some classic rock. Anybody with any information on the MIM classic "standard" vintage Pup's and/or suggestions please respond. TIA.
