The Gibraltar 9811SGD 9000 is a responsive chain-driven pedal, with smooth action and many great features for ease of use. The Stealth Series bass drum pedal board has an independent height adjustment that does not affect the spring tension or beater angle. The hoop clamp tightener wing nut is located at the top, making it easy to attach the pedal while seated. It has a quick-response rocker hub spring assembly, aluminum base, and a dual-surface black and chrome 90-gram beater. It also comes with a backpack carrying case. This pedal is used but in very good condition. It retails for $199, but I am offering it for $88 plus shipping.
