The GuitarHeads Mini Rail Humbucker is the perfect solution to putting a full size humbucker into the single coil size slot. Each pickup features 2 Coils for true humbucking operation, and the Rail design eliminates "drop out" when bending strings. The tone offers clear highs & crunching lows, and has a high output that will cut through the thickest mixes. The Mini Rail is driven by an Anisotropic Ferrite Magnet (a High-end Ceramic), and is Wax Potted for Microphonic Suppression. These pickups also feature a 5 Conductor Lead, allowing you to Tap the Coils for alternate wiring. Also included are Mounting Screws & Height Adjustment Springs.
