Ok... i remember last time I looked that the angle up from the capo was around
12 degrees. Bridge pins were angled at 10. Didnt check downbearing but I can if
needed. The angle up from the aggraffes in the bass was a bit less then the
capo area, but I havent measured that.

I would be glad to measure anything you would like on this if it will serve the
discussion.
