Can someone tell me if the Alembic jazz bass type pickups will work with another brand of eq?for instance Bartolini,are the pickups active,or could i just use them in a standard passive jazz bass?thanks .

The pickups are low impedance and require an onboard preamp.

Do they need voltage to them also?or just a preamp,thanks.

yes you would  need a 9 Volt.

The pickups most definitely do not need voltage, however the preamp does - that's why the 9V connector is attached to one of the circuit boards in the picture that Keavin posted.
 
You need a preamp because the Alembic pickups are low impedance, which is a mismatch for any instrument cable (which will be high impedance).
 
You'd need to check if the preamp is designed to handle low impedance pickups.

That's what i needed to know,thanks.
