Yamaha makes some amazing instruments, particularly pianos. But when it comes to their student-line acoustic guitars, you can get SO much more bang for your buck with Canadian brands like Seagull, and Alvarez guitars. I've never owned a Yamaha acoustic guitar but I have taught MANY students over the last 12 years who had these as starters, and they always disappoint. Trust me ... shop around.
Oh man, there are definitely some horrible super low end Alvarez but their middle line is so cheap. I got an excellent acoustic-electric Alvarez, brand new, for under $200 at a local shop that was trying to move product so, maybe elsewhere it might run as high as $300? but it sounds like a $600-700 guitar. I've played some (not many, but some) Larivee and Taylor acoustics that didn't hold a candle. Great tones, perfect for stage gigs.
Hands down the best acoustic I've ever owned. Found it at an antique mall. It was covered in stickers that ate away the finish, and the body was split along the joints. The previous owner repaired it with hot glue. Almost caught on fire, carried case-less through rain, sanded part of it for a little percussive scratch pad. Now, I'm too scared too string it with steel, so I use light nylon. Such an amazing tone from this particular one. I've not found another like it.
The Yamaha F325 is great guitar for beginners, this was my first acoustic guitar, as I got more adept at guitar, the more I noticed the problems of this guitar. The action is high, the sound is thin. The tuners are sub-par... But for all this, a beginner will have this guitar and cherish as the quality of this affordable guitar is miles ahead of other guitars in the same price range.
