So I just purchased my brand new Gibraltar Avenger 661DB Double pedal yesterday, I tried it out and it was pretty good. But when I was playing it earlier one of the beaters would clip off, so i thought it was the locks problem so i switched it to the other side. But then it also ended up clipping off and flying off while I played with it. Is there a way to fix this problem? or is this a defect of the beater and should I get it replaced? Thank you for your answers!
