so DISASTER strikes
i took out my geddy lee pickups to check the pole pieces align with my string "strings" and the placed bridge.
The rear pickup cavity has been routed for the smaller front pickup. Surely everyone knows that the rear pickup is larger on a jazz bass ? (excepting very early mex basses where the front is the same larger size as the rear, but even that doesn't fit this case)
Raised a dispute/return request with the ebay seller. I'm a bit annoyed at ths.
