... Rock Band 2 offers an unparalleled, deeper, dynamic gameplay experience. This package includes a newly designed guitar and drum peripherals, with spiffier detail and a more realistic playing experience. These are all fully compatible with the original Rock Band instruments. The Guitar is sturdier, with a more precise strum bar, a built-in sensor allowing quick and seamless calibration, a retooled tilt sensor for improved Overdrive employment, a more realistic neck and body design, and quieter buttons. The Drums have an improved kick pedal with metal plate, velocity-sensitive drum heads, cymbal and hi-hat expansion ports, quieter drum heads and a wireless connection. Distributed by Tubemogul.
