This twin coil design pickup gives you the character of our 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. You can expect great harmonics and a sweet high-end. Compared to Hot Rails, the output is reduced and there’s more treble response. Comes with four-conductor hookup cable. USA Patent No. Des. 355,207.
