The Keller Difference
As a leading drum shell manufacturer for nearly 50 years, we know what it takes to build long-lasting, high-quality shells. In fact, many of the quality drums and kits from the 60's and 70's were created with Keller at the Core. All of our drum shells are made from 100% choice North American hard woods that have undergone rigorous selection and screening processes. In addition, they are created using our state-of-the-art stagger seam lamination process.

About VSS Drum Shells
VSS™ (Vibrating Sound Source), a patented Keller Products innovation, uses space-age technology to condition each shell.  VSS™ technology results in regenerated vibrations that elevate head response and increase drum performance thus delivering a wider tonal range, more resonant frequencies and increased volume for longer, louder and warmer sounds.

VSS™ enhances the integrity and strength of the drum shells and provides manufacturers with cleaner entry and exit for drilling, more consistent bearing edges, and improved stability for finishing. Players can expect drums that start with VSS™ shells to deliver a wider tonal range, more resonant frequencies, and noticeable volume increases.
