The GuitarHeads Megametal Humbucker was designed with the super shredder in mind. The Bar design will accommodate string spacings from 48mm to 54mm, and eliminates "drop out" when bending strings. The raw & thrashy tone is packed with tons of output, and harmonic ability. The Megametal 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.
