In 1979 Yamaha introduced the FG 750S and the FG770S. By this time, the S in a model number no longer meant Sunburst as it had previously and now referred to a solid top instead. Although they were considered mid range, they essentially became the highest range FGs at the time because the all the highest speced FGs had become the L series. Enough Yamahistory. The solid top Yamahas from that era have had 40 odd years to 'open up' in terms of tone and they sound beautiful. This guitar has been setup with new strings, low action, conditioned fretboard etc etc. It plays as well as it sounds. A lot of people that talk about acoustics talk about old Yamahas and seem to like comparing them with Martins i.e this is a Martin killer and so on but after collecting, playing, and souping up hundreds of them over 30 odd years my own experience is that for 10% of the price of any big name guitar, you get a shitload more than 10% of the tonal quality and build quality by comparison and yes, sometimes they're better depending on which guitars you're comparing. It will always be subjective and in many ways pointless but it's worth saying that vintage FG Yamaha guitars are fantastic value for money.
