Yeah, I’m wanting one really badly. I’ve got a nice handmade, all solid wood Yairi 12-string but it’s just too light on the low end. For some reason the F512 seem to be much more rare than the F412. I actually prefer the F512 I think, just because the 412’s curly maple is so ostentatious. The F12 is a little more subdued cosmetically.
If you ever get either one. you won’t be sorry and would have very little problem reselling it if you did.
