I have SD Alnico II's on my Gib LP Studio. I'm trying to put the cover that was on the stock p-ups onto these. Do I need to put wax on top of the Alnico II's? And what's the point of the wax? And also, when I solder them onto the covers, do I use a certain type of metal? or will any do...? Thanks!

To do this, you'll need to solder the covers to the back plate of your current humbuckers. Use 60/40 lead tin solder. With a rosin core.

Yes you need to wax pot them. You'll find several tutorials here, and on projectguitars.com.

Why does a pickup need to be potted? Otherwise, the cover, and other parts, may vibrate when played at a high volume. This causes feedback.
