I ordered a Tusq nut from StewMac.com. Just be sure to order the right one. I installed Seymour Duncan pickups and Mad Hatter Guitar Products Terminator push-pull pots, switch and input jack. No soldering required. I take plenty of flack for it, but I don't mind one bit because I like the sounds I get. Ed at Mad Hatter will guide you thru the process. If you really want to solder, practice with some spare wire and metal of the right dimensions.
