The Tama HP30 Stage Master Single Bass Drum Pedal gives you pro results and will save you money. The HP30 features the same offset cam design as the Iron Cobra Power Glide. Offering more speed and power at the end of the stroke than others in the same price range. More bang for the buck. Easily adjustable beater angle usually found only on higher dollar pedals, along with a spring tension adjustment for more control over the rebound. The new DS30 beater has 2 different textures to offer 2 different sounds. The felt side provides a softer more focused sound, while the plastic side gives greater attack for a punchier, louder sound.
