Seymour Duncan JB Jr. SJBK-1b Bridge Pickup in White This Pickup gives you the character of the JB model Humbucker pickup but in a single coil sized housing. It's 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! Great harmonics and sweet high end is what you can expect.   Specs 4 Conductor wiring 16.09k Resistance? 3.6 KHz Resonant peaking Ceramic bar
