Guitar Czar has some of the most knowledgeable employees in town. They really will come off as arrogant and rude if you go in acting like you know everything, but let them do their thing and they will typically spend some one-on-one time with you and give you some good advice and information. The only complaint I have about Guitar Czar is they are understaffed. If you drop your guitar off for a set-up (intonation, action, truss rod adjustment etc) it will take two weeks minimum before you get it back. I think this is because one guy does all the set-ups and they are backed up all the time. Meanwhile, House of Guitars gets your guitar back to you the next day. This isn't a huge problem because Guitar Czar's work is higher quality.
