Re: Duncan Antiquity Aged Nickel Covers WANTED!
Joneser, don't bother. Well, maybe I shouldn't say that, but results vary all over the place with etchant solution on pup covers. I've had many more that I tossed than I kept. Works fairly well for other nickel plated parts tho. You have to watch it carefully...takes seconds. And again, yields erratic (but better) results. The problem with covers is that they're all of different quality, and most of them suck. The polepiece holes (edges) will corrode faster than the rest of the pup, if you're dunking them. The plating is thinnest there, apparently. You can buy aged covers from RS Guitarworks, I forget what they cost, but I don't think they're too pricey. I'm pretty sure that Ant covers are nickel-silver, like the old ones were. I know Seths are.
If you do try aging some, make sure they are clean. Wear gloves and wipe them down with lighter fluid (naptha), to get rid of any oils, fingerprints, etc.
