I've noticed on ebay and some other places that there are a decent amount of replacement nuts floating around, any suggestions for a replacement? I'd like to get something for my SE CU24 that will give me a little more tuning stability when I use the trem. Also, if I got a precut/slotted one, is it something I could replace myself or should I take it to a shop? I do my own wiring, pickups, setups, etc, but the fretboard and nut are one area I steer clear of because I lack the tools and skills to fix any problems I would probably create...
