Never seen a P-neck with that truss-rod head ..
Was if added by Mr. Halliday of thd truss rod fully replaced?
Could post clear picture of the headstock front and back please?
The pickups are Fender Samarium Cobalt Noiseless (SCN) noiseless jazz bass pickups.
They’re known as Fender SCN bass pickups.
They sound clear and noiseless for modern JB tones connoisseurs!
