New Composite Shell Technology from Grover Pro Percussion
July 11, 1997
This exclusive technology now features a pre-impregnated manufacturing process which
offers precise control over wall thickness tolerances. Through a new heat treating
process, resins are chemically unified with a synthetic fiber (E-glass) to form a
thin drum shell with significantly enhanced resonance. During this process, a
cross-linked reinforced composite is created which increases durability and strength
by 40%.
"No other drum manufacturer currently offers this state-of-the-art manufacturing
process," stated Andrew Rega, vice president of operations. "Our new Composite
Shell Technology process creates a virtually indestructible, thin drum shell that
resonates with a distinctive, powerful tone. Our CST Series Performance Drumsets and
Snare Drums offer drummers an alternative to the traditional sound that wood shells
produce."
Performance Series drums feature die cast "coffin-style" lugs with rubber
bushings that allow the shell to vibrate freely, precision bearing edges for minimal
head-to-shell contact, 2.3mm hoops isolated with nylon washers, and a nodal venting
system which places an air-dispersion vent in the drum's "sweet" spot (near
the bottom drum head) to produce a faster transient attack. Performance Snare Drums
also features the new Performance Snare System non-spiral snare wire for increased
projection and sensitivity and a Gladstone-style throw off.
In a drum shell analysis at a professional Boston recording studio, the resonance
of Grover CST drum shells were tested against several Maple drum shells. The results
indicated CST shells to be 2.5 times more resonant than Maple shells. To request more information, contact David Kilkenny at 617-935-6200. Check out Grover Pro Percussion's website at www.groverpro.com. |
