I recently took this guitar off the wall rack in my home studio where it sat for 2 years and played it and  stayed nearly in tune, it was only a flat from standard E tuning. I always like this guitar better from more expensive because price, quality, and tone. Upon purchasing this guitar, cuz I neeeded for a classical class that I took back then, I changed the strings to D'addario pro arte hard tension and the sound gain a richer tone. Even my instructor who was a hardcore classical player noticed. Im so happy with my Yamaha, So glad that I purchase it instead of a $fifteen hundred dollar Ramirez..
