I'm looking to get some opinions or experience with the Seymour Duncan SJB-2, if anybody had used them. I am not looking for alternative suggestions, so please only input on this particular pup. I am intrigued by the increased output and strong midrange specs. I am considering this set for a fretless J-Bass. My concept is to beef up the midrange and sacrifice some the clarity in the low/treble range, since those frequencies won't be strong on a fretless w/ flatwounds anyways. Rated output is 15 kohm Neck and 16.6 kohm Bridge according to SD's tone chart. That's a lot for my taste in passive J-pups, but they could sound real great in fretless w/ flatwounds?
