Make friends with your local thrift store. We don't keep them at my store because they don't sell but we still get rock band drum sets about every other month at my store.I just have no fucking luck. I bought a couple of new drum pads for my old RB2 kit and they worked wonderfully until my red one completely busted off the kit. like this.
I've had my kit since RB2 launched and I never had any real issues until I started using them for RB4. The rubber bubbled and came off 3 of my drums a couple years ago and I've done various fixes to just keep the thing alive for as long as possible and now I just have no idea what to do.
