The Throne Thumper is a vibration module for electronic drums that can be attached to any drum throne and is compatible with all E-Drums. A motor converts the low frequencies produced while playing the E-Drums into vibrations that the player can directly feel through the throne, providing a tangible resonance. Each bass drum hit is not only heard but also felt! Delivery does not include a throne. The vibration module connects to the included Throne Thumper amplifier, which is controlled by the E-Drum set. The amplifier features a volume and low-pass filter control, allowing the player to adjust the vibrations as desired. This way, snare and toms can also be felt. Details: compatible with all types of E-Drums/E-Drum kits, fits any throne, easy to install, power: 200 watts.
