There are 6 different samples/mic placements; each was roughly 1 to 1.5 feet away from the top of the bass, and parallel (more-or-less) with the top. With that, I varied the lateral/vertical positions of the mic:
1. roughly even or slightly below the bridge, a few inches outside the treble leg
2. up a few inches but still lower than the fingerboard, and in closer to the fingerboard (still on the treble side); mic rotated down slightly
3. up yet more inches, higher than the fingerboard a few inches, and right next to the treble-side of the fingerboard; again, rotated down slightly
4. similar to #3, but on the bass-side of the fingerboard
5. mirror of #2, bass-side
6. mirror of #1, bass-side
(edit: counting is hard)
I was a bit surprised that the mic placements closest to the bridge sounded the most dull, and those furthest away sounded the brightest. After thinking about it, though, I'd theorize that it's really likely there's a concentration of non-vibrating nodes near the bridge in the top plate of the instrument box because: 1) there's the most downward pressure from the strings, 2) the arch is highest at that point, and 3) it's also the narrowest point of the body; because of that, more vibrations entered the mic capsule off-axis at that point, and became more on-axis as the mic position rose. It's just a theory, though; I am neither a luthier nor an acoustic engineer, and I play neither of those roles on TV.
