This is a great selection of musical instruments combining our extremely popular and great sounding RotoGen Piano and Acoustic Guitar, with some great percussion accompaniment. The set is supplied with aluminium T-slot posts that will allow you to create your own layouts with the 45 degree post slots. Human powered energy is the kinetic power source for RotoGen products, making them self-sufficient and self-contained electronic products that do not require any hard wiring for power, or any batteries changed on a regular basis.
