Seymour Duncan JB Jr. (SJBJ-1)

Very hot, tight and aggressive, with a dark top end and tight lows.

Hotter than 88% of the 153 neck Strat single-coils we have

  • Ceramic magnet: the strongest pull: tight lows and a sharp attack
  • Darker than a typical Seymour Duncan
  • Tighter lows than a typical Seymour Duncan

“The JB Jr sounds like it has great crunch on the bass, good mids but way too ice-picky treble.”

Seymour Duncan JB Jr. Why I dislike it.

“It is actually voiced much better for punch and clarity in a neck position that one might expect.”

“Sort of that sweet spot if you think the Hot Rail neck has too much brawn and the Little 59 neck has too much spank.”

“The JB Jr sounded bright, almost glassy and the mids seemed, well nasal, if that makes any sense!”

“The Jb Jr is awfully bright and kinda bass deficient in the bridge.”
