I am terrible at the guitar.  (A)

In this case, can "at" be replaced as "with" or "on" ? which becomes:
I am terrible with the guitar.  (B)
I am terrible on the guitar.  (C)

Rre ABC all correct ?    what are the differences among them ?

Answer

We normally use "at" when talking about skill, talent or ability, e.g.:

good at
not great at
average at
capable at
bad at
lousy at, etc.

Answer

Mr. Montage's correct. There indeed is, some subtle difference among the preps. I mean in semantics.  Also there might be slang, dialectal, etc reasons for it, eg to me some Africans might be more likely to say "on" than "with", I myself know a guy saying "good on" a lot.

Answer

All forms are excusable and would be understood however the best form is:

I am terrible at (playing) the Guitar.
