Thought I'd post some photos of my most recent four string mandolin tuned GDAE. Its a 14.5" scale and could also be tuned CGDA. Construction is maple and purpleheart. Its a hollow body with a block below the bridge. I used this as the "test" piece for my eventual full size guitar version. No obel. Just a passive system. Also, special thanks to Bob for his tips on the brass inlay on the top.
