Great store, nice layout and atmosphere. The staff is mostly very knowledgeable, however one of them got angry at us for trying out some drum sets (I'm guessing it was because we were being loud, but how else are you gonna try a drum set?). They can advice you with your purchase no matter what level of play you are at, which was really nice.
They have a nice variety of products, and have basically EVERYTHING you might need (except for classical instruments, but that's for other stores to cover).
Their clinics are really cool and valuable to attend.
Overall, a VERY good store, one of the best in Calgary.
