Tama Standard Twin Pedal HP30TWUtilizing the same offset cam shape as the Iron Cobra 900 Power Glide, the HP30 offers increased power and speed with an easily adjustable beater angle a feature usually found on top of the line pedals. Offered with the DS30 beater, two different sounds can be achieved by rotating the beater head: the felt side for a softer, controlled sound, or the plastic side for a louder and punchier sound with more attack.
