Yamaha DTXpress/DTXplorer/DTXtreme

Not on stage, heaven forbid (Nate uses a Roland TD-20 incorporated 
into his kit), but in one of the practice rooms the "contestants" were 
hanging out in during pre-show stuff.  I almost knocked over my drink 
to yell out to my wife, "Look, there's a Yamaha kit!!!", but common 
sense (and maturity) got the better of me.

On second thought, I think it was a DTXtreme set.
