Seriously?

Isn't this one of those "you could"s that is really a "..but you *could* win the lottery"?

Again, ESD blowing up LEDs? I've never even managed to blow up a CMOS 4000 series using ESD. And I did try, although I don't wear many artificial fabrics. A 9V battery was required, and even then I had to do it wrong. Now *that* works for LEDs too.

I'm not really trying to knock what is probably technically correct advice, but it just sounds all rather over the top for what is just an LED at the end of a long wire. It's not like we're running a life-support machine off this jack lead. The worst case is the synth player has to wave his hand in time in the unlikely situation that the LED boxes die.
