This is a 3-Way Tele prewired assembly for Telecaster style guitars with Humbuckers or P90's. It will drop into most Mexican or American Fender Teles with little or no modification. Wired with 22 AWG vintage push-back wire for that vintage look and sound. Soldered connections to the input jack are insulated with heat-shrink to ensure durability and long life. If you are installing this on an import guitar with metric sized pots you may need to ream your control plate holes to accept the slightly larger US-Spec pots and buy US-Spec knobs.
