The Saturn Evolution Classic Maple 4-Piece Shell Pack in Exotic Azure Burst Lacquer includes the revolutionary "Halo" mount, a lateral, unique "under lug-line" suspension system. This feature unlocks the freedom of full resonance and allows the drum to sing with an open, pure tone. The Adjustment Knob acts as a built-in Equalizer that can slightly dampen the resonance of the shell, producing a tighter and quicker decay. Whether you like to go dry in a jazz gig, or sound huge in a packed arena, the Saturn Evolution has the whole package for you.Configuration:8" x 10" Tom9" x 12" Tom16" x 16" Floor Tom18" x 22" Bass DrumSnare drum available separatelyCymbals and hardware not includedRack tom holders (shown) sold separately_Features:Halo Mounting System - The revolutionary new "Halo" mount featured on all Saturn Evolution toms, unlocks the freedom of full resonance. Using a lateral, unique "under lug-line" suspension system, this new groundbreaking isolation mount allows the shell the freedom to have an open, pure tone. This is done with minimal stiffness usually associated with under hoop mounting systems.Adjustment Knob - With the rubber gasket inside the mount, you can screw the knob down fully to dampen the shell resonance for a shorter decay, or back it off for a wide, open tone. In the studio, this allows you to "pre-EQ" your drums before feeding them into your plug-ins.Maple/Walnut Hybrid Shell - The iconic Saturn Maple/Walnut hybrid shell has been inhered with Design Lab features and SoniClear Attenuation System to provide you a fuller, rounder tone with Bright, Versatile, Open sound.Chamber Specific Design - Plies get progressively thicker, depths graduate by 1/2", and bearing edges change as the drums get larger in diameter. The combination of all of these details creates an amazing symphony in one kit, where each and every drum sounds perfect!Sp
