Difference between Givens A3 model and Givens A4 model?

[Josh Levine]

Hey folks, lots of info on Givens mandolins out here, but was wondering if someone could weigh in on the difference between the F hole A models A-3 and A-4. As I understand it, neither have fingerboard binding, but otherwise I don't know the difference.

Greg Boyd at Boyd's House of Fine Instruments would probably be the best source for answering such a question.

Either that or Steve Weill who worked with Bob for several years.
