3 prong conversion - shocking question

I receive a lot of e-mails about 3 prong conversion, death cap and the usual 'my amp zap'd me'. We have some info in the archive section of this site, but here is a link on a nice thread that cover most of the topic - and also address the 'isolation transformer' to be or not to be.

And here's another cool link that summarize the topic quite nicely (at least for us players) and there's a walk thru for the DIY conversion.
