Amen to Kevin. All due respect, I cannot for the life of me understand how anyone could have any difficulty using a capo.

I have come to accept that some folks have legitimate difficulty with the basic arithmetic required to figure out what key you're in with a capo in a given position (which always seemed pretty simple to me). But claiming inability to use a capo at all ~ I don't get it. Must be some kind of irrational mental block, perceiving some kind of difficulty that doesn't really exist.

If you don't like the sound of the guitar capoed up a step or two or three, you're not going to like its sound with the strings tuned up a step or two or three. Same sound. (Except for the sound of wood splintering, if you tune the wrong guitar up too high).
