My new guitar I got a couple of weeks ago came stock with a JB/59 set. I've never used SD's before, only EMG's. I play mostly thrash kinda music, lot's of downpicking and triplets, all rhythm. I really liked the JB at first but now I'm realizing it doesn't have what I'm looking for. Which is less bass, more crunch. I've tried this thing on ever amp I own and it doesn't sound great on any. I want to stick with SD's, not switch to EMG's. So I've read a bunch of opinions on here but still can't figure out what kind of pickup I need. Seems like the two most popular with users are the Custom and Distortion. Could use some help deciding.
