A Premium Prewired 4-way Control Kit Upgrade your guitar's switching system with the Emerson Custom 4-way Prewired Kit for Fender Telecaster and similar guitars. This kit's premium components include precision-made potentiometers, an Oak Grigsby 4-way switch, an Emerson Custom Paper in Oil Capacitor, a Treble Bleed mod to prevent your tone from getting muddy when you turn down the volume, and a Switchcraft output jack. They have been prewired and soldered, so you can drop them in your guitar with minimal work. Every Emerson Pro pot is hand-metered in-house and falls within ±8% tolerance, and the capacitors are the only new MIL-Spec capacitors in production in the US.
