What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Damping amount is set by you, so you can go from light control to heavy thud without swapping parts.
Detail 02
Sized to a 20-inch bass drum specifically. It will not seat correctly in a larger or smaller shell.
Detail 03
Sits inside the drum, so it stays out of the way of the pedal, beater and front head port.
Detail 04
Cheaper than a new pre-muffled head, and it stays with the drum when you change heads.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is the 20-inch version and is built to that shell diameter. Use the size that matches your drum.
You need access to the inside of the shell, which means removing the front head. Plan for a few minutes with a drum key.
Yes. The system sits inside the shell and does not replace or block your heads.
It is sized by diameter, not brand, so any 20-inch bass drum is the target. Fit depends on your shell, not the badge.
