Yamaha G-80A classical guitar custom
This is a wonderful early guitar Yamaha made before scaling their productions. Compared to its 1970s counterparts it is more responsive, maybe thanks to its ultra-thin and lightweight yet durable clear finish which allows for the instrument to vibrate and resonate more freely.
I have re-tuned the braces to make the guitar even more resonant.
The oval sound port on the side of the guitar allows the high frequency to exit the body of the guitar giving a more balanced sound.
