The year might be helpful, eh?! its a 1998 model. Guess I'm gettin' old ;)
I'm begining to think the Gibson pickups I have are possibly 498/490. I've found that when installed by Gibson, they come with the two wire, but when sold as replacements they are four wire. Either one was available with nickel covers. Guess my next step is to buy a multi meeter and get a reading on each.
In the end, I think its safe to rule out these being 57's... they are likely the 498/490.
Thanks for the help!
