Jazzmaster Wiring Harness w/Rhythm Circuit (500k Pots)


We've partnered with the best in the business, 920D Custom, to build the ultimate custom Lambertones wiring harnesses to compliment our pickups.

Harness Name: "JMH" Jazzmaster Wiring Harness w/Rhythm Circuit

Works with: "the Crema" for JM Set & "the Ristretto" JM set


There are two reasons why this harness is for you: 

(1) You're tired of the single-coil hum and want to install our JM "Crema" humbuckers. 

(2) You've decided you want the ultimate dynamic and articulate single coil experience and are installing "the Ristretto" P90's in your Jazzmaster.

Both reasons are valid for a replacement of your stock harness, and this does not disappoint. Nothing was spared in this custom wiring harness build specially for us at Lambertones by our friends over at 920D Custom in Arkansas.
