For a 'real' guitar, I would try a close XY with the flat plane of the
mic bodies perpendicular to the direction of the neck. Put another way:
stand the guitar straight up, and XY fairly close in (6"?), probably
where the neck meets body. Plane of mic bodies parallel to ground. Now
rotate everything to accomodate the non-horizontal guitarist.
