I have a '72 black, fretless Ric 4001 that appears to have a bad bridge pickup. I've had it since '75 and it worked fine until a couple years ago. I have no idea what happened. I opened it up today to see if I could find a bad pot or solder joint, etc. Everything checked out as far as I could tell. I used my multi-meter to test the leads from the pickups. The neck pickup showed 7.7k Ohms and the bridge pickup showed infinite. I didn't unsolder the pickups, but I figured since I got those readings, that the bridge pickup must be "open". Anyway, what would you all suggest? Buy a replacement (where?), get it rewound (where?), other...? I'd like to preserve the value since this bass is not that common.
