I'm in the beginning stages of building a 'Frankenbass' from parts I have laying around, including a pair of Basslines active pickups. Before I go too far, how would I check that the pickups are good? What I was thinking was to connect a 9v battery to the wires and check the output. But, being just knowledgable enough with electronics to cause damage, what should I be checking for? Ohms, amps, voltage? Any help on this would be appreciated!
