Yamaha's KP65 kick tower pad gives you the natural playability and greater musical expression you want from your electronic drum kit. The KP65 houses advanced capabilities you just don't find on the average electronic kick drum pad. Using the input connection on the back of the pedal, you can connect an external pad to add versatility to your sound. There's also a knob that adjusts the pedal's output level to increase/decrease the pad's response sensitivity. With this knob, you can tailor the KP65 to your playing style, tweak the pad's dynamic range, or better match it to the type of trigger module that you're using. And Yamaha made the playing surface of the KP65 kick tower pad large enough to suit a double bass pedal setup adding even more flexibility to your kit.
