The Gruv-X Mundo Cascara Plate is a handy accessory that gives you an alternate playing surface for cascara patterns or anything else you might play on the shell of a drum. It also has the same features as the Gruv-X X-Click.The Mundo Cascara plate is a hybrid formula of 24-plies of American rock maple and copper with a proprietary new design for mounting, called the “Mono Mount”. This revolutionary design gives expanded volume and boosted low-frequencies to the cross stick sound on any drum. This helps the cross stick tone with execution consistency and also gives it a better “nominal listening value” (or common volume) to the snare drum backbeat sound. This helps audio engineers by eliminating the need to ride the snare drum mic channel, live and in the studio. The Mono-Mount fits drums from a 10” 6 -lug, to a 15” 8-lug and everything in between.
