I really like Sam Ash since it is a one-stop shop for anything musically related. They have a huge selection of instruments, accessories, sheet music, and equipment. They even have a stage in the middle of the store!! They can be a bit expensive, however they literally have anything you will need, so it's worth the extra buck. It's a bummer that there is only one store in the valley, and it's in the ghetto. I wouldn't come here at night, since it can be sketchy.
