Roland TD-4 Sound module with cable, mounting plate, mounting arm for TD-4 KP rack, and Power Supply. Works perfectly but two of the rubber buttons show signs of wear and work as they should. Metal pole mounting arm for a rack and a flat mounting plate are also supplied. The loom that is with it is in excellent condition and has been electrician tested without any issues whatsoever. The unit has also been PAC tested and passed. Thanks for looking.
