This Yamaha G-50 (1968) Classical Guitar was made in Japan. It is a much higher grade guitar than the more recent one, much better than those made in the 80s and 90s, and much better than the cheaper Taiwanese made G-50s.
I've fine-tuned the bracing to make it even more resonant.
I've also installed a Fishman Sonitone Pickup Preamp on it for performance and recording use.
Fishman Sonitone Undersaddle Pickup features a soundhole mounted preamp with rotary controls for Volume and Tone. The Fishman Sonitone delivers a dynamic and natural sound and features two controls: volume and tone. The preamp is discrete-looking, in fact, most people won't know the guitar has a preamp until you plug it into an amp. The single knob tone adjustment is a preferred option by many classical guitarists as it's simple to use and will always give a beautiful, natural and balanced sound.
This is also a prefered option for the more expensive classical guitars as people prefer not to drill too many holes into their guitars.
Since only one hole is needed in the frame for the jack, the acoustic resonance is hardly affected.
This guitar is loud with broad bass and clear trebles. It has a typical much sort after the sound of early Yamaha acoustic guitars.
People describe the early Yamaha guitars as being able to cut through the mix during recording sessions and live performances.
The guitar has some signs of normal wear. I'd say it's in fantastic condition for being 53 years old.
