Ion Drum Rocker Rock Band 2 Cymbal Expansion

The cymbals are awesome, all there is to it, makes it a more realistic drumming experience!

and I know alot of people have problems, specifically, the cymbals will get to where you hit the cymbal once, and it registers 3-4 hits. I had this problem as well, but it's a simple fix, or was for me anyway, look under the cymbal, see all those screws? Just tighten them up a little. It fixed my double-triple hit problem. They come loose with play, thus when you hit, the screws will cause enough vibration and the sensor thinks you have hit the cymbal more than once. Hope this helps people!
