the wires that connect tothe 3-way switch on my guitar are not connected to the switch, like the soldering was very good. i was woundering about how much this would be to fix?

Not much. Almost free if you do it yourself. Soldering irons only cost a few bucks, and solder wire is cheap. If you don't reckon that's for you, I don't see a shop charging more than £10/$15.

Could be wrong, I do all that stuff myself.
