This is a 14" x 6.5" snare drum with a 10mm thick, 8-ply maple shell. It's a maple model from the "Z Series," and is considered one of the most powerful wood snare drums in Pearl's history. It's wonderful that this masterpiece from the 1990s, embodying "overwhelming power and sound pressure"—the complete opposite of modern lightweight snare drums—still exists in such beautiful condition after more than 30 years.
