Custom Solderless Jazzmaster wiring harness can be made with 1meg lead circuit or a more modern 500k potentiometer configuration( a popular after market mod for Fenders) Rhythm circuit is standard. Harness does not come with a pickguard but you are most welcome to send me your pickguard for me to wire the harness on. For any custom options such as upgraded pots, switches etc or modifications please get in touch.
