The Emerson Custom Les Paul Kit with 550K Long Shaft Pots for Gibson USA Les Paul Standard Models delivers authentic 1950s-style wiring handcrafted in the USA by Emerson's founder, Mitch Ingram. This prewired harness features four 550K Premier Pro hand-metered potentiometers, a Switchcraft J11 input jack, and Bumblebee paper-in-oil capacitors (0.015µf neck, 0.022µf bridge) for vintage-correct tone and feel. The 50's style wiring produces a stronger, tighter, more transparent sound with reduced treble loss when rolling back volume, responsive controls without hot spots, and interactive tone and volume adjustment—allowing you to clean up overdriven amps while staying present in the mix. Includes wiring diagram for easy installation on USA Gibson Les Pauls.
