The result is a virtually indestructible, thin drum shell with a distinctive bright tone and ultra-sensitive response. Precision DNC Bearing Edges Utilizing automated DNC technology, Grover machines all bearing edges and snare beds to extremely close tolerances, resulting in optimal drumhead vibration and drum shell resonance. DNC technology measures the density and depth of each drum shell and machines a custom bearing edge and snare bed accordingly. This custom process results in precise drumhead seating, easy tuning and a consistent attack and decay across a wide dynamic range. The close tolerance of DNC technology assures perfect placement of all mounting holes.
All hardware fits tightly with no air leakage.
This allows for a faster transient attack while the multiple ports precisely focus and contain air dispersion to maximize the drum's decay. Piston Strainer One of the greatest features of the Projection-Plus snare drum is the Piston Strainer and Snare Outrigger System. This system features a 5-point adjustment feature that lets you tension the snares both laterally and vertically. We adjust each drum to factory specs to insure maximum articulation and the ultimate in snare sensitivity. Our GIS Indexing System allows you to note your strainer settings for consistency, or in case you need to change settings during a performance.
