Roland PD125 V-Pad

The Roland PD125 V-Pad is a digital drum pad designed for use with electronic drum kits. It is a 12-inch pad with a velocity-sensitive rubber surface and a built-in trigger. It is designed to be used with Roland's TD-25, TD-30, TD-50, and TD-50KV drum kits. It has been used by many professional drummers, including Travis Barker, Chad Smith, and Dave Grohl.

The Roland PD125 V-Pad works by sending a signal to the drum module when it is struck. This signal is then processed by the module and sent to the sound module, which produces the sound. The pad is velocity-sensitive, meaning that the harder it is struck, the louder the sound will be. It also has a built-in trigger, which allows it to be used with other drum modules and sound modules. The pad also has a built-in LED light, which can be used to indicate when the pad is being struck.
