Re: The static discharge...
If I were you, I would ground anything and everything that the player touches... such as the steering wheel,
pedals, control panel, and possibly buttons. This may require the use of some thin metal inserts & or strips..
which you then can attach a grounding bolt, and ground all the wires to the cabinet strip... then out the ground plug.
At best, all you could do for the Ipac for safety is make a metal mesh cage. However, thats more for static in the air, and
to protect anything from dropping on it.
You want to stop the static at the controls, and cabinet, before the surges can get anywhere near the electronics.
