It features three dynamic 8 inch. tom pads - a 8 inch. dual-zone snare drum for great feel and natural response, plus a kick drum pad with pedal. Three 10 inch. cymbals, including a crash with choke, give you a virtually unlimited range of playing expression and the 4-post aluminium mounting rack keeps everything solid and secure.

The Nitro module is filled with sounds - and surprises. The backlit LCD screen makes navigation a breeze. Drum and cymbal buttons are arranged to resemble the layout of a traditional kit, so it's simple to assign sounds and create kits quickly. The Nitro module comes complete with 40 classic and modern ready-to-play kits. Easily tweak any existing kit, or create your own using the 385 superior drum, cymbal, and percussion sounds included in the Nitro module. Inside the Nitro module you'll also find valuable extras. The built-in learning features, sixty play-along music tracks, and an onboard metronome allow you to improve your skills.
