Description
The JB Trembucker is the F-spaced sibling of Seymour Duncan’s most famous humbucker, reworked with wider pole piece spacing so it lines up correctly on guitars with tremolo bridges or modern post-1999 Gibson bridge routing. Under the hood it’s the same hot-rodded design as the SH-4, just repositioned for these bridge layouts.
Seymour Duncan has kept this pickup in his own arsenal for good reason: it covers an enormous amount of ground. Dial back and it breathes with warm, articulate clean and edge-of-breakup tones; push it into a cranked amp and it delivers slamming output with aggressive harmonic content and a satisfying wall of sustain and distortion. It works equally well for heavy blues phrasing and full-on metal riffing.
Compared to the SH-14 Custom 5, the JB pulls ahead in treble detail and bite – if you find that top end a touch sharp for your rig, swapping to 250K pots is a common trick to smooth things out without losing the pickup’s character.
- F-spaced (Trembucker) version of the classic JB humbucker
- Comes wired with four-conductor hookup cable for full coil-splitting flexibility
- Recommended for the bridge position
- White cover finish
Players often pair the JB in the bridge with an SH-2n Jazz in the neck for a versatile two-pickup setup, or an SH-1 ’59 when chasing classic P.A.F. warmth on the neck side.
