I got myself a new epiphone about 6 - 7 months back. I love the guitar, but the pickups are a bit flat. Any suggestions for possible upgrades would be greatly appreciated. I play blues primarily, and I'm looking for something with more punch than I can get out of the stock epiphone pickups. I've listened to some of the online examples (seymour duncan) to get some idea what I'm looking for . I think I'm leaning toward either the JB SH4 for the bridge, and the Jazz SH2 for the neck, or the Pearly Gates. Has anyone tried these on a semi-hollow body, and if so, how'd it work? I have no experience at this kind of stuff and would greatly appreciate any help.
