No comments needed. Immediate purchase possible. I used this for about a year after purchasing it, but I am selling it because I switched to an acoustic drum set. As this is a used item, there are some scuff marks on the back and some beater marks on the striking surface from normal use, but these do not affect its use. Sound output has been confirmed. Features The KP100 is a kick pad that improves quietness with a slit structure that creates grooves on the upper and lower inside of the striking surface. The three-layer structure with materials of different hardness creates a comfortable playing feel. The base of the kick pad is designed to be large for improved stability. Specifications ■ Kick Pad ■ Sensor System: Trigger Sensor (Piezoelectric Element) x 1 ■ Output Terminal: Standard Stereo Phone Jack ■ Input Terminal: Standard Mono Phone Jack ■ External Dimensions (when assembled for actual use: including protrusions): 340(W) x 288(D) x 464(H)mm (when assembled) ■ Weight: 5.0kg ≪3-Layer Structure that Creates Optimal Response According to Striking Force≫ It has a new structure with three layers of materials of different hardness. The softest material is used on the striking surface, and harder materials are used towards the back, allowing for an optimal playing feel depending on the force of your foot. This structure creates an unprecedentedly comfortable playing feel for the bass drum, which is essential for drummers. ≪Slit Structure that Reduces Vibration Transmission During Striking≫ The KP100 features a "slit structure" with grooves on the upper and lower inside of the striking surface. By creating these grooves, the vibrating part when the foot pedal's beater hits the striking surface is minimized. This structure reduces the spread of vibration across the entire striking surface during impact, improving quietness. ≪Large Diameter Pad Suitable for Double Foot Pedals≫ The striking surface is a large 10-inch diameter, making it easy to set up double foot pedals. The base of the kick pad is designed to be large, providing a wider contact area and improved stability. [From Sound House Product Description] Sound House Price: ¥41,382-
