Bad ground?
Bad power strip?

Yeh the SICK! bit sounds a bit stupid.

Amp would be the most likely choice. check for 3 pin plug, as mitythor said.

The questions people ask here makes me wonder how the TS's dress themselves in the morning and can shower without drowning...
Just to let you know....

A while back I thought i was getting shocked by my bass. I checked everything throughly and could not find any reason why something would shock me. It turns out that I had a pretty bad case of Carpal Tunnel. Haha, yeah that is most likely not your case though.

Could you describe a bit more as to how it's shocking you? What kind of gear and setup are you using?

It's shocking me through the strings.
I'm running my guitar straight into my amp most of the time.
I use a V-Amp 2 every now and then, I run that through the effects loop.
It still shocks me.
It usually happens after about two minutes into my playing.

And, yes, my amp has a grounded, three-pronged plug.
Huh... your gear must hate you.

Make sure the ground wire from the bridge of your guitar didn't come disconnected.
