This ddrum Hybrid Bass Drum is a fully functional acoustic kick drum that's been augmented with industry-standard Acoustic Pro triggers - shock mounted to the interior of the drum, with your cable plugging into the shells' integrated XLR connections. This allows you to take full advantage of electronic options for sound reinforcement and replacement. With their superb tracking ability, ddrum triggers set a new standard of trigger mechanics. Pro Series Triggers are internally mounted into the Hybrid. They provide a wide dynamic range, easily replaceable transducers, rugged metal construction and increased sensitivity for accurate response.
