Playing the Yamaha F 325 is overall pretty comfortable. I've found it to be a pretty easy guitar to play, especially for one that is supposed to be for beginners. If you are a beginner who is looking for a guitar, it's especially important to get a guitar with playability as it's going to be the place where you form all of your habits. Having a guitar that feels good is sometimes half the battle for a new player, and you'll definitely get a nice feel with the F 325.
The sound of the Yamaha F 325 isn't really anything to write home about, but it's not awful by any stretch. It has a good enough sound to get the job done for simple playing and practicing, but it isn't the type of guitar I'd do any real recording with outside of demoing songs. It's more or less full bodied in terms of tone, but if you were to play it side by side with a higher end guitar you would notice the difference pretty quickly...
Overall, the Yamaha F 325 is pretty much the perfect guitar for the player who is just starting out and is definitely useful for more experienced players as well. It's more than playable and has a pretty good sound for a beginner's guitar. Yamaha is the largest instrument manufacturer in the world, so it's definitely not surprising that they can offer a guitar of this caliber for such a cheap price. If you're in the market for a guitar to get started with, the Yamaha F 325 would be a great choice.
