FG465

You are correct.  It must be a rarely rare model with uncommon sycamore top/back/side and an uncommon finish.

Post some pics!

I'm finding a couple of hits for the FG-465 saying James Taylor guitar, but I doubt he would play a low end model like this. It listed for $430, probably sold for about $300, and it doesn't even have a solid top as other models of the time do.  He played the L55 & FG-2000, much higher end models, before moving to Olsen guitars.

It's interesting that so many people talk about just about any model FG and say it is the best guitar they've ever heard.  That goes to show the quality of guitars that Yamaha makes.  Most of us will never get to try any of the high end Yamaha's to be able to compare with the common models.  I'm sure they're at another level, but are they worth another 5 to 10 times the price??
