Hi Mica,
I have two troubles on my old alembic bass.
One is 1983 series I bass.
Serial is 832854.
Front pickup does not work.
No sound heard from front pickup.
I believed PF6 circuit is OK.
Because I heard no sound from rear pickups
when I did swap front pickup for rear pickup.
I measured pickup resistance.
Front pickup was 3.6M ohms.
Rear pickup was 1.6K ohms.
I think Front pickup coil is wire break.
Two is 1975 series I bass.
Serial is 75AE015.
Hum canceling pickup does not work.
Previous owner tried to repair a coil.
But He gave up re-wiring.
I have its hum canceling pickup but it was taken apart.
I want to solve these problems.
I am living in Japan.
Oversea transporting is very expensive and high risk for my basses.
If I send you these pickups, would you exchange or repair them?
