The general consensus is that you have to get used to a Rickenbacker. What does that mean? Is it neck shape? Is it body shape? Is it some kind of odd proportion? What is the deal with that? I have never touched a Ric, let alone played one, but I'm really curious about them, especially since they have a reputation for being so polarizing. I have never seen any kind of explanation of what all this really means. In ergonomic terms, why is this?
