The above is good advice, but if you do end up deciding you want new pickups then maybe look at the Entwistle PBXN and JBXN. I've always said the PBXN is very much like the SPB3 but with slightly more mids, and although I haven't tried the Seymour Duncan 1/4 Pound J, the Entwistle J has that same vibe going on as the P.
Absolutely go with the 1/4 Pound range of that's what you want as they're great, but the Entwistle Neo's are just as great at a fraction of the price.
