This is one of the cables from my No~Shock~Zone demonstration class. Don't get too excited... there's a 100K current limiting resistor feeding pin-1 on the XLR with pins 2 and 3 also bonded to it. It's one of the cables I use to test Non Contact Voltage Testers for sensitivity on hot microphones. A mic with 120-volts on it will usually cause a NCVT to light up and beep from 4 to 6 inches away. Makes a great demonstration.
The cable looks pretty scary, doesn't it? I pulled it out of my school bag last week during a live-sound class, and the students went nuts. Too much fun... :o

You KNOW you really want one of these for when some drunk offers to sing with the band... :o

Needed this cable last night at a bar gig I helped set up for one of my music buddies. Why do drunks always think they can sing? :-X
No, I didn't use it... but just thinking about it gave me a warm-fuzzy feeling.
On a side note, I forgot just how much interference/buzz those neon beer signs put out. The one guitarist had a single-coil electric guitar which buzzed like crazy unless he spun around about 120 degrees from his playing position. It was hard to convince him that this buzzing had NOTHING to do with ground-loop hum since the system was dead quiet with everything else running. More to study...
