For all your musical needs, I suggest you check out Kings Music which is located a few blocks away from the Kings Plaza mall. They have everything you need from guitars to drums to sheet music. They are open seven days a week and they provide you with a fantastic service. They even offer lessions for many instruments. Parking isnt great in the area but you should be able to find something. Plenty of buses go around the area so that is always helpful. Their prices are very good too which is always helpful to your wallet.
