the bridge: guitar or vihuela?

I still regard this instrument -  and its ancestor the Belchior Dias instrument - as a vihuela.

When I was working on the bridge however I made up a way to devide the sting-holes in a manner that would accomodate both stringing with 6 courses as a vihuela and with 5 courses as an early guitar.

The second hole (i.e. the first of the d'-course) can equally be used as e' for the guitar.

Transforming the instrument to guitar thus only require a set of strings. Might be worth while to try.

I don't have a baroque guitar (yet).....
