These are Vintage ’72 Wide Range Humbuckers built to fit Jazzmaster guitars. These use the same vintage correct bobbins and threaded magnet/Alnico combination as the Vinage ’72s but mounted to a Jazzmaster sized base. The threaded pole pieces have 54mm spacing in the neck and bridge and are fully adjustable.

These mount the same as stock Jazzmaster pickups and require nothing special nor any modifications.
Like the stock Vintage ’72 both the neck and the bridge are wound with equal number of turns. If you want the neck under-wound for better balance between positions please let me know. The “underwound Neck” checkbox is for an 8.8k wind to go with stock JM pickups or to retain more Jazzmaster qualities.
Bridge & Neck: 10.7k
Underwound Neck: 8.8k
