Single-pedal with a robust base plate with built-in spikes and a rubber pad for firm stability. It is simply attached to the drum rim with a clamp. The advantage is a very simple adjustment of the spring tension for easy adjustment of the resistance of the beater, which has two surfaces: one transparent plastic for a larger attack and types of soft felt for a more vintage tone. The foot pedal is smooth and provides a quick response. The double chain ensures smooth running. The tuning key is included in the package.
