Advanced Bass Muffling System (for Marching Bass Drums)

The foam is cut to cover the entire inner circumference of your drum, attaching immediately with a professional-grade adhesive that sets instantly (no more waiting time to put new heads on).

We brainstormed with the biggest names in marching percussion to make sure the thickness of the foam corresponds to the size of the drum to give you exactly the right amount of muffling. A specially-designed angle on the side that touches the head ensures the foam remains completely in contact with the head when you add tension, unlike straight foam that leaves a small gap.

This product includes two strips to fully dampen both sides of any marching bass drum. *The exact inner diameter of the drum can vary slightly from manufacturer to manufacturer. We give you enough to cover any brand's drum, so there may be a little too much foam. The excess can be easily trimmed off.

Using foam for muffling marching bass drums has been the go-to method for drumline's around the world for quite some time now. With over 50 years of experience in playing, tuning and muffling bass drums, our experts have all agreed that this is the formula that works. This system has the right density of foam, the optimal amount of contact with both the head (to reduce overtones) and the shell (to keep shell tone quality) and, best of all, the easiest and most accurate installation. The angle cut of the foam is a proprietary design to ensure that you get full contact between the foam and head, unlike your regular square cut foam. The adhesive is immediate yet adjustable during installation and holds strong so you can put your heads on and get back to what we all love the most, playing bass drum. 

There is simply nothing else like this on the market.
