Awesome example of Tiger with Dual Sounds! Just goes to show that different years produced different results with different tweaks within his gear. He was the overall constant, but that rig was always evolving! Also check out Healy's Maestro Mic on the 4th bottom speaker, it has a basket reversed.
Thanks for posting!
Here is another example from 89 @ 1:07 - 1:18
