I was never happy with my EMG Hz's in my Schecter Custom 4. It had a very hi-fi zingy sound that I think perhaps would be good for metal, but I appreciate a more vintage tone. The bass, on the other hand, plays great and is very lightweight. I thought about selling it, but the resale was not very good, so... I bought a pair of Seymour Duncan Basslines SSB4's, took out the EMG's and the preamp, put in some 250K pots and a Radioshack DPDT miniswitch for a series/parallel toggle. I guess I could have forked out a little more cash for a matching gold switch, but I like instant gratification and went to Radioshack These Basslines totally changed the tone of the bass. It's much more full, and rich, with a warm tone that has quite a bit of burp/growl to it. It is more "vintage" but just by the nature of the humbuckers it's much more "modern" than my jazzes, for example. (I know, apples and oranges). There are definitely less highs than the EMG's had and there is no boost to compensate, but I never have needed that zing. When I pop/slap, it still sounds great, but not over-the-top clanky. Overall, I'm very happy with the change and I've turned the bass from a closet relic to something that I think I'll play out with more.
