I'm teaching myself to solder to replace pickups, pots, etc., and have read lots of threads here and elsewhere for tips. One thing about which there seems to be much disagreement, though, is whether a mechanical connection should be created before soldering a wire to a pot terminal. Most folks seem to just lay the wire against the terminal and solder it in place, but others suggest wrapping the wire around the terminal and through the little hole in the terminal to create a mechanical connection before soldering. This makes senes to me -- i.e., for a strong mechanical as well as electrical connection -- and doesn't seem difficult to do. Besides, what else is the little hole in the terminal for? So, which way should I do it? And particularly, what is the argument for NOT doing a wrap-and-twist first?
