Jody, I have seen Paul Geremia play several times and my recollection is that he played a normal ( Martin type) twelve string as opposed to the (Stella type) twelve string you describe.

I am not claiming infallibility however and my recollection may be totally faulty, so since you are obviously a friend of his perhaps you could ask him again if he does in fact use the Stella type twelve string exclusively?

Regards
