Thanks T.Y. So I now know I have a 1982 model, do you know where I can get parts for it? I need a couple of frets replaced and would like to replace the individual saddles on the bridge.
You will probably need to take the guitar to a luthier to have the frets replaced. That's a pretty sophisticated DIY job. If you want to try and tackle it go to StewMac.com. Good resource for luthier equipment. Also, if you buy the equipment to replace a couple of frets you will also want to level and crown the frets so they "match" the older frets. Again, a lot to do for a DIY job.
Re: the individual saddles. I have done this job by cutting each piece using a dremel tool. You need to copy each piece exactly or the intonation will be off. Again look over the Stewmac site. I bought a bone blank and cut away. Get two, you will likely make a hash of things the first go around.
