The Roland PD-108-BC is a 10" electronic drum with a replaceable mesh head. This is the same drum that comes with the TD-30KV kit. Want an additional 10" tom for your kit? This is what you buy. Want to upgrade your older toms to the newest Roland design? We do trades let us know. This drum comes with a cable and owners manual. It will work best with the TD-30 module but will also work as a dual trigger drum on most Roland modules.
