"Pearl offers a variety of Bass Drum Beater options to suit the needs of players in any musical setting.
Demon Drive Control Core Beaters are available in felt (B-300F) and wood (B-300W) and feature an elastomer center for vibration control, increased power and better energy transfer from the pedal to the head.
DB-100 and DB-150 DuoBeater options offer the sound and feel of both felt and solid plastic beaters in one convenient pedal option. Choose a punchier, more giving attack with the felt beater or the slapping, powerful strike of the Plastic beater (a sound similar to traditional Wood beaters).
For the ultimate in versatility the B-250QB QuadBeater provides four different beater surfaces, each with its own distinct sound. You can choose from 2 hard plastic surfaces or 2 felt surfaces and either pinpoint or line contact with the head."
