Rock Band 3 pro drums are a lot of fun, but as soon as I started playing, I noticed a big problem: My blue and green cymbals were over-hitting (i.e. being struck only once but registering multiple hits), and they were doing it a lot. Holding a 4x multiplier was just impossible in a lot of songs. And even in songs that were mainly snare/bass/hi-hat, as soon as I'd hit the green crash to activate overdrive, that 8x multiplier would turn into a 2x.

I spent a while fiddling with the screws that hold the cymbals down on the supports and control their tightness, and that helped some. Instead of over-hitting every single time, no matter what, I got it so they wouldn't over-hit as long as I hit them softly. Better, but still not practical on fast songs.

After a couple minutes of googling to see if others were having the same problem, I came across the penny mod. I also found several posts that said people had talked with Mad Catz support on the phone and had been pointed to this mod as a possible fix that wouldn't void the warranty, which I think is pretty cool. So, I decided to give it a shot and got out my screwdriver.

Ten minutes and two cents later, I now get zero over-hits on my blue and green cymbals, even when whacking the green hard at the end of a drum roll.
