True to the vision of their pioneering founder, the new Ludwig Atlas Pro Bass Drum Pedal is built for a whole new level of performance. All appointments are infinitely adjustable for precise, customized feel and lasting stability. Starting with the option of a long or short chain, this pedal offers a wide range of adjustment options from the beater to the footboard to spring tension. This pedal also offers fast, firm and durable performance by way of a machine-tooled stainless streel drive shaft, a Monarch dual-chain drive cam and SpurLok heel plate anchors. And when you're attaching this pedal to your kick drum via the multi-positioning hoop clamp, the drum key stored on the baseplate will enable you to do so in one motion.
