Quoted from drummermike:I put the shaker in my Houdini myself. Took 20 minutes. Love it! I have had no issues with it shaking the pin apart. I have had it a while now. I put a shaker in my standard LOTR also. My ST pro has one and my LAH. Love all of them.
I agree - it really adds to the experience. Love how the Elephant stomps shake the machine as an example.
