So yesterday I got a pair of used Nordstrand Jazz pups in the mail, so I shieleded my bass and then proceeded to install the pickups. Traditional V-V-T set up, I plug it in dead silent. I'm thinking I am hot **** because there is no hum at all, I restring it then plug it in so I can test out the new pups and it's DEAD. Nothing sounds, I fiddled with all the knobs and I couldn't get a peep out of it. I opened it up again and fixed the only thing that I saw as wrong (the bridge pup was installed backwards) and well it's still dead. The only time I can get any noise out of the bass through my amp is unplugging it. So electronic gods and wizards of Talk Bass, please come to my aid.
