Hi Franck, for a series bass you need the true single coil Alembic pickup which is the SC-1 w/hx . The AXY pickups are hum cancelling pickups and are used in the Stanley Clarke and Mark King signature basses.
The series basses use true single coil pickups and a separate hum cancelling coil and electronics in the bass body to get rid of interference.
Whether an AXY would still work I could not say for sure but I imagine you would have a problem getting the hum cancelling system to work effectively with two different types of pickups.
If you make a call to Alembic, Mica will be able to provide you with the right answer. I can't imagine the cost of a new replacement Series pickup would be much more than the ?300 set of AXY's i've seen on ebay.
