You gotta be more specific. Yamaha if a big company and many of their instrumentsa are made all over the place. From India to Pakistan to Korea, China and Japan. It really depends on the type of guitar you want, how it's made and where it's made. Personally I have never come across a factory guitar made outside of US or Japan that was any good. I had a Yamaha acoustic when I was younger back in my classical gutiar days that was nice, but then I had an RG model (which they don't make anymore) wich was an amazing guitar top to bottom, but then it was made in the '80's when guitars were made right.
RG Then -
24 Frets, Floyd Rose locking trem, dual Duncan humbuckers, neck tru construction, 13 degree angled headstock, Alder body
RG now -
22 Frets, non-locking trem, 2 humbuckers and a single coil of no decernable brand, bold on neck, straight headstock, poplar body
RGX (the supposed, upgraded, modern version of the RG) -
22 Frets, bolt on neck, hardtail bridge, soapbar pickups, for some reason they changed the headstock.
My advice. Play them and feel for yourself. If you wanna not spend much on a student guitar then sure. As for their more high end models that people actually want to play, they stopped making those a while ago. I used the RG as an example because I liked these. But it's the same story for bassists John Myung, John Pattatucci or guitar god Frank Gambale leaving the company and their signature models.
