I have to take my tremolo arm off of my guitar (IBANEZ) every time i put it in my case.

At the moment I have a soft case, but if i buy a hard case will I have to take it off every time I put it in?

(sorry never had a hard case before... kind of a noob question i know)
Yes, you will. You should take it off whenever it's in transit anyway, if it gets whacked the wrong way or caught on something it could mess up the trem or break the arm off in the socket.
