This video, via alternatingbitmusic, takes an in-depth look at the Synthetic Sound Labs Thundrum, a 5U analog drum synth module.

The ThunDrum 1140 is a two oscillator FM percussive membrane / metal based drum voice, in a single width MU module (Dotcom-compatible Moog Unit).

As the video demonstrates, ThunDrum is designed to let you create a wide range of classic analog drum synth sounds – along with more experimental sounds.

Details on the Thundrum are available at the SSL site.
