Thanks ya'll, that'd be Rusty Sanner's Falcon that is 'dual-key'. Three sets of reeds for per key and the bass stop is to switch keys as well. Personally don't like them because they sound bare without the high bank for each key on the treble side. I'm sure they're great for performances, and they look pretty awesome, but I'd rather have a multitude o' boxes with the high bank. Rounds out the sound nicely.

Without the high bank? Isn't it a mid bank missing?

Awesome, Cam.

always thought it was the high missing, but I could be wrong... either way I'd miss whichever is missing

That's some dang fine shootin' Cameron
