The new XP120SD is designed to be the most realistic feeling electronic snare drum to date. Yamaha has used a newly designed Textured Cellular Silicone head to achieve this. The head is built by introducing tiny air bubbles into foamed silicone in a proprietary manufacturing process. The results are the XP120SD which has a different stick rebound than a tom. The drum is 12" and 3 zone and ships with a stereo cable to hook it up to your module. This drum is fully compatible with the DTX900 module and the Dtxtreme III module when upgraded to the proper firmware.
