Hey, with descriptions like this, who wouldn't want one?

Shock wave generators are capable of producing focused acoustic or electromagnetic energy that can break up objects such as kidney stones and other similar materials. EMP generators can produce pulses of electromagnetic energy that can destroy the sensitive electronics in computers and microprocessors. Destabilized LCR circuits can produce multi megawatt pulses by using an explosive wire disruptive switch. These high power pulses can be coupled into antennas, conic sections, horns etc for very directional effects.

Funny thing is, one of these would probably fry the barely-functioning radio in the Spider, but otherwise it would start and drive off like nothing special had happened.

Well, when it starts, that is.
