Evans 20" E-Mad Reso Bass Drum BK

The concept is great, and the sound is good and deep (tried combined with the EMAD Batter head), controlled - especially with the hole damper mounted. A nice touch is that the hole edge has a ribbon of extra plastic mounted around it, so mics or damping materials moved through the hole will not snag and tear the drum skin.

However, the hole damper is made out of fragile foam with nothing to hold it together on the hole side - which means that if you move the damper around, the skin will start to carve into the damper and eventually the damper will separate into two useless sides. This didn't take long, even when just using the particular kick it was mounted to in a personal studio with me being the only person to touch it... Live it will be impossible for the damper to last even 2 teardowns, I think.
