In this clip, you’ll see a ‘lethal Scopeboy modification of a Tesla coil for guitar amplification [250,000 volts]’. Video after the break.

Tesla coils consist of two, or sometimes three, coupled resonant electric circuits. Tesla experimented with a large variety of coils and configurations, so it is difficult to define a “Tesla coil” as one specific mode of construction. Tesla used these coils to conduct innovative experiments in electrical lighting, fluorescence, x-rays, high frequency alternating current phenomena, electrotherapy, and wireless power for electric power transmission
