HI, 
Perhaps someone here can give me some advice. 
I recently bought a used Squier IV deluxe jazz bass which worked ok for a short while and then the electronics failed completely. There is some output but is very very low. 
There is a battery powered active eq pcb fitted so I guess this has failed............, can anyone here tell me................ are the pickups passive and if I rewire them to normal tone and volume pots will they work or do they require battery power, i.e some kind of preamp. 
Thanks for any help, 
John
