Very similar to the JB Model in a Strat® size. Adjustable pole pieces.
The Seymour Duncan JB Jr. is a twin coil design pickup that gives you the character of their popular JB Model Humbucker in a single coil size. Its adjustable pole pieces more closely emulate the magnetic field of a full size humbucker and allow you to fine tune the balance of your strings: a first for a humbucker this size. You can expect great harmonics and a sweet high-end.
