The Mars Series Shell Pack offers 100% Birch shallow depth shells with the new SONIClear bearing edge that produces a fast, clear tone with a quick rebound. The Birch 6 ply 7.2mm shell with the new SONIClear bearing edge allows for the direct transmission of sound, reduces unwanted frequencies, and provides a strong fundamental pitch and an effortless tuning experience especially at lower tunings. The SONIClear tom suspension and floor tom feet increase overall resonance by preserving vibration in the shell and keeping stress away from the tension rods, helping the heads stay in tune. The Mars Series "Rock" Shell Pack features sizes that can span a wide range of playing styles. This configuration offers a blend of power and versatility well-suited for the drummer needing a portable, great sounding kit.
