Hi Matt,
        Thanks for the reply.  You can't get the total 13th chord on the
guitar, but you get an approximation of it as follows:
strings       fret          finger   note
6              3              1       G
5              x              x       x
4              3              2       F
3              4              3       B
2              5              4       E
1              5              4       A
The little finger bars both the E and the A.  It's a nice jazzy alternative
to the usual dominant 7th.
        Thanks again for the interest.
