Wow, 10v? Body resistance must have been very low to feel that. I can't remember the exact amp I was using (I think it was an old PPI PC2350 - 2x350w@4ohms) but I could only feel a slight buzz and that was at ~60vrms AC on the speaker wires in bridged mode.

Most people don't realize that it's the body's own reaction that kills them most of the time. It takes ~15mA (that's 0.015A) to severely hurt/kill you. Example: Take 120V. If your resistance is ~15Mohms, that's only 8uA (0.000008A). Ok, so you feel it, but it doesn't harm you. But, the body's reaction (heart pumping faster increasing circulation closer to the skin, sweating, etc) all lowers the body's resistance, which makes you react more, which further lowers the resistance until it gets to a point where that magic 15mA can start flowing and that's where the problem lies. If you could remain totally calm and somehow keep your body from reacting in this way at all, it would theoretically take 225,000V to kill you (assuming 15Mohm body resistance and exactly 15mA to be fatal).
