Ah GC my go to place when I need some new equipment for my drums. I do like GC because they usually have what I am looking for and if I have to special order something it is usually there pretty quickly, so I will give them props to that, and I don't think that they are too overpriced like some people may think.
What I don't like about GC. One they don't offer every type of name brand instruments. 2, the staff are usually still stuck in the 80's and I can usually out play all of them. 3, people trying out equipment who just suck at playing. It's god damn annoying.
But in all seriousness if you need a piece of equipment for recording, dj'ing, lighting, amps, keyboards, guitars, or drums, they will have a good enough selection that you can definitely get by and have a great sound!!
