Guitar Center La Mesa
I have come here every few years when I want to buy a guitar or new strings, sound accessories, et cetera. I am not too much of a fan of the huge warehouse approach to music shops, but I can see why some people would like the many options to choose from and the very "tech" feel to the shop. The prices are pretty good for new gear, especially around the winter holidays, when they know a lot of kids will be asking Santa/Hanukkah Harry for a guitar, so there are usually good deals/packages around then. Overall a pretty decent store.
