So here I am revamping a '94 Squier Series Jazz Bass. I got a new control plate--probably cheap Chinese-made components, but the cost was worth the control plate alone. I'm finding here's a lot of hum. I know single coils will be somewhat noisy, but it seems a bit more than necessary. I've shielded the inside with aluminum tape (using a multi-meter to ensure it is connected throughout). The tape completely silenced by P-Bass, so I'd like to do the same here, at least to some degree. I'm wondering if some of the samarium cobalt noiseless pickups and some new wiring will be an upgrade over the stock J-bass pickups in terms of silence. I've never used them personally, but I can get a set for $65. Both pickups in this bass are 3 and 5/8," so I assume It'll need a bit of widening in the bridge pu slot. Thoughts?
