I got this with my new catalona club jazz's and dont know what to do with it.
My guess is that it clamps to the bottom on the bass drum rim, and the bass pedal clamps to it, allowing the bass drum to be elevated a few inches off the ground.
Note the bass drum in the photo below. The front & back are raised:
It's so you can use a regular kick pedal with an 18" kick. DJ has one.
Yup. Bass drum riser.
