I use to have two bass drums when I was younger. Later I got a new set with a single bass. Purchased a double bass pedal and have no idea how to anchor the floating left pedal. I built a drum room, purchased the sound proofing materal, drum mics, mixer. Right now there is just concrete on the floor so there is defnite slippage immediately. I have to purchase some more rubber mats for the floor (Since my old set is under my weight apparatus). But I am looking for a more secure method of anchoring the pedal. Any ideas or products out there?

Thanks
