My most memorable shock was 36v at 400hz.
I was working on a servo on the 06 deck of a warship, about 60-70 feet off the main deck, out on a skinny catwalk. Hot sweaty day, grounded six ways from sunday and I laid the soft part of my forearm on a terminal strip. The "jumpback factor" had me hanging on the rail, over the side, with one arm. I managed to regain my composure and get back up on the catwalk but I was sweating a little more.
These days I sum up the experience by reminding people, a GFCI may keep you from being electrocuted but if you fall off the ladder ... ;-)
