The feel of this guitar is fluid and the action is quite low, which makes it really easy to play all around the neck. It isn't the lightest guitar in the world, but is light enough and easy to carry. It has an awesome look and overall shape to it and the overall tone is versatile and vibrant.
While this guitar is called a Jazzmaster, I've never actually used it for jazz music. I have used it mostly for pop and rock. This being said, it would definitley work well with jazz and a number of different genres as it has a great overall tone and is suitable for a variety of applications. The clean sound is great - I usually use it with a '76 Fender Twin Reverb and the sound is crisp and quite vibrant. I also use it with a bit of overdrive, but have found that this guitar isn't best for heavy distortion.
The Fender Jazzmaster is one of my favorite guitars as it feels great to play and also sounds awesome. All of the controls it has on the body allow you to alter the sound in a number of ways and you can get a variety of sounds with it. The price is pretty reasonable if you can get one used and won't break the bank at all. Overall, my favorite part of this guitar is the neck and is really feels great. Fender makes arguably the best guitars in the world and this model is a prime example.
