7-pad electronic drum pad with 2 pedals Thank you for viewing. This drum pad operates on AAA batteries. It also supports USB external power. Since it does not have a built-in speaker, you need to connect headphones or speakers to produce sound. This is a used item, but it is in a condition with little signs of use. I was able to confirm its operation by connecting speakers. Manufacturer unknown. There is no instruction manual, so the detailed operating instructions are unknown, but it can be used intuitively. This is a set of pads and pedals (batteries, power cable, and speakers are not included). For shipping, it will be rolled up and packed to the extent that it does not affect the quality.
