Joey Kramer's brass shell drum is physically much heavier and has a deeper, darker fundamental than Miller's steel drum. The die-cast hoops are potential stick-splitters, but enfold the sound more, so that although loud (the keystone badge says 'hit hard') the effect is less unruly than with the steel drum.
It has a fatter and warmer tone with more snare and less clank. It's expensive, but it looks fantastic and is refined, capable of a wide tuning and dynamic range. Tuned high or low it sounds good: tuned way high the enunciation was so clean it was a joy, while at medium tension there is a majestic, warm, thick snarey fatness - a stadium beater. Please note the small factory imperfection on the throwoff. Small white mark, totally smooth, not a gouge.
