about 6 months back i nearly killed myself working on a guitar amp that was cleverly still plugged into the mains. The voltage came in through the index finger of my right hand and actually cooked my flesh in a weird pattern before exiting via my thumb which luckily was grounded. The cooked area looked exactly like roast chicken
Theres nothing like mains voltage electrocution, feels like your body is going to vibrate itself to pieces.
