The GuitarHeads Super Twang Series Pickups for Telecaster style guitars offer a traditional Quack & Twang. The Bridge Position Version is glassy & hot, but still can clean up nicely. The Super Twang is driven by an Anisotropic Ferrite Magnet (a High-end Ceramic), and is Wax Potted for Microphonic Suppression. This pickup also features a Copper Baseplate, traditional 3-Screw Mounting, and standard 2-Wrie Conductor Lead for easy wiring & installation. Also included are Mounting Screws & Height Adjustment Springs.
