With its swayless stability and sport-bike-inspired visuals, the Yamaha FP9 double bass pedal delivers style and performance that can please the industry's most discriminating players. Front and rear spikes and a frame-inside-a-frame design, prevent rocking, sliding, and pedal play of any kind. This results in a smooth, nearly 1:1 transfer of energy, even at high intensities. Yamaha's 3-way Quick-Adjusting Links, paired with independently adjustable footboards and beaters, make the FP9 a pedal tweaker's delight. Features we at Sweetwater found especially helpful are the FP9's self-locking ergonomic spring tension knobs, which make it fast and easy to dial in each side from playing position. You also get a weighted beater system with removable weights to further dial in speed, throw, and power. A carry case is also included.
