TB4J JB Seymour Duncan Vintage 1990 Humbucker hand-wound by the legendary Maricela Juarez

Up for sale is a highly sought-after vintage 1990 Seymour Duncan TB4J JB Model Trembucker.

The "J" sticker on the back confirms this unit was hand-wound by the legendary Maricela Juarez (current head of the SD Custom Shop). Vintage Duncan pickups from this era with the "J" stamp are famous among players and collectors for their distinct harmonic richness and mojo compared to modern production models.

As a Trembucker (TB4), this features the wider pole-piece spacing designed perfectly for guitars equipped with Floyd Rose or vintage tremolo bridges (like Charvel, Jackson, Kramer, etc.).
