Hello quick question. I have a Double White Gibson Pickup. It's reading 8.49k. It came out of a Custom Shop guitar and I currently have it in a 58 Korina Reissue. It's paired with a BB2 in the bridge. Anyone know if it's a BB3? or 57 or 57+. I know kinda hard to say with out more info. But I had a chart for Gibson pickups and I can't find it and can't remember which one falls into that range. Someone is interested and wanted to know what pickup it was and when I pulled it all that is there is the GIBSON USA logo.

I'm pretty sure BBs and 57s do not have two rows of pole screw holes in their base plate.
The 490, 498, and Dirty Fingers have two rows of screw holes.
Dirty Fingers are really hot (measure appx 16K Ohms)
Based on your reading, it could be a 490T
