Big, Serious Electrical Problem!!

Ok so today I recieved the worst shock of my life, ever.

Let me rephrase that. I wasn't shocked. I was flat out electrocuted.

So I was playing bass in my drummer's room with the band, just plugged into a tiny little practice amp, like 30W, the one that came with my first bass, and we were playing and everyting was going alright, then we stopped playing and started talking. So subconciously everyone has a tendancy to touch their surroundings while their distracted and talking, so there was a stand-up lamp next to me with a side attachment that had another light, one that you could bend and move, but basically just a regular stand-up lamp, plugged in and on. So all that I remember was I was holding my guitar, we were all still on and plugged in, and I inadvertantly grabbed onto the side attachment to the light. That was one of the worst mistakes I've ever made. All I remember is soon as I grabbed that, I stopped hearing everything around me, and every muscle in my body tightened up and I started seizuring, badly. The worst part is, when I say every muscle tightened up, I mean every muscle, including my hand which was still holding onto the lamp. So it instantaneously got so tight that I couldn't let go or control anything, and I had no idea what was happening, I just knew that something was wrong and I started slowly screaming "Oh my god!" because I really had no idea what was happening to me. When you get electrocuted and arn't even expecting it, you don't even realize that its electricity doing it to you. I felt like I was dying. The only thing that stopped it was I convulsed so bad that I actually threw my guitar across the room about 10 seconds after I first started getting shocked, and then the current stopped. When I actually thew my guitar down, the base part hit the bottom of the lamp, and some major sparks flew from where the two touched. So I think that for some reason touching the strings on my guitar and the lamp for some reason made a circuit and I was unfortunate enough to get caught in the middle of it. But being the curious monkey I was, without my guitar this time, I touched the light, and there was nothing wrong, no shocks or anything, and the light still worked, and my guitar still worked (because I went and played a show with it 2 hours later).

I mean, I've heard of, and even experienced, two guitarists touching each other if we're both not wearing shoes and holding our strings and we can get a tiny little shock, but I never imagined something this bad could happen from that.

I dont know what the electronic specifications on my guitar are, but something wasn't right, and I want to know what so that never happens to me again. My Guitar is a Schecter Stiletto Elite-5 with active electronics and passive EMG-Hz pickups.

Please if you have any idea what happened, please let me know.

first off...if you WERE "flat out electrocuted", you would be dead...by definition, electrocution is death by electric shock

if that ever happens again, get a mate to take you to the hospital IMMEDIATELY....your heart can do some seriously funky things (like STOPPING) even long after an electric shock...because the electricity throws your heart rhythm out of whack.

Get that amp and lamp both checked out by a licensed electrician...one of them is NOT earthed properly!

DANGER! SERIOUS DANGER!

Finally...get yourself a decent RCD (aka GFI) protected power board, and never leave home without it.

Good info here.... but I might add a couple of touch-ups....

I'm not sure how it's done down under, Pilbara.... but in the US, lamp cords are almost never grounded, or "earthed". They simply use the 2-prong AC connection.

What I suspect happened is... your amp has a good ground (3-prong plug), one which carries through all the way to your instrument cable/bass/strings/hands..... you touched the (probably) cheaply wired, cheaply constructed, non-grounded, non-GFCI'd lamp... current which was powering the lamp either arced, or was already shorted to the exterior of the fixture.... and the current shot through you, to the good ground provided by your bass and amp.

Dude, you're lucky to be posting tonight.

And while the GFI (or GFCI) that Pilbara mentioned is a great idea (I never play without one), it likely wouldn't have helped here - unless the lamp had also been plugged into it - because it was the lamp's power circuit which "leaked", not the amp's circuit.

Moral of the story: always be EXTREMELY careful what you touch while holding your bass. GFCI's can help greatly, but they only protect you from the devices that are plugged into them. When you're playing, make sure that ALL gear - especially the gear that the mics are plugged into - is powered through the GFCI (or touching a hot mic can cause a repeat of what you experienced today).

And, by all means - if it ever happens again - get thee to a hospital to be checked out.
 
I NEVER EVER plug it without checking the outlet. You can get one of these for like $2-3, and it can save your life.

very true, bigbeefdog...

In Australia, all homes built since 1997 or so have a "safety switch" basically a residual current device (RCD) for ALL power points.

The National Electric Code in the US needs a serious update in that it only requires GFI's on power outlets outdoors, in bathrooms, and in kitchens....

why not just do the whole house and be done with it?

My folks' home in Pennsylvania was built in 1960, and until recently most of the outlets were only 2-prong...(no ground except to the metal box)...:(

we humans learn slowly....

you're better off not posting, ok?
The OP was hurt pretty badly. He was not even being careless. I've taken some pretty bad shocks myself in band situations and in the military.. they aren't at all humorous.

Bingo. I'd bet money that you're diagnosis is exactly right.


brendanbass, if your drummer hasn't already, tell him to trash that lamp ASAP. The next person this happens to might not be as fortunate as you.
 
someone should sticky a warning or something pretaining to this sort of thing, seriously, because I had no idea this could happen and no one ever told me, and half the people I talk to still don't know about it. It's a hazard that should be adressed somewhere
 
Would a tester have helped in this situation? I got the impression it was the lamp's faulty wiring and not the house's.

Not in this situation, no (assuming my "diagnosis" is correct).

Still, there are many other potentially dangerous situations that can be detected with a tester. It's a must-have item for the gig bag.

And don't get me started on playing off generator power (hint: ALWAYS ALWAYS use a GFCI pigtail when doing this...).

I have heard about this but have always wondered a few things:

1) How does the amp not get damaged? If the signal was 110V (US) through the signal jack, wouldn't that kill the input ciruit and smoke the amp straight away? I mean, they only handle a fraction of that peak, right?
2) How does a current of that magnitude jump from the hand to the strings to the (presumably) pickups? The body is wood, which is a poor conductor and the wires in the electronics are too light guage to hold 110v/15A... maybe not? Surly even the pots in the bass wood be destroyed after that, but again, I guess not.

You assesment seems logical, but I have always wondered about this.

Get rid of the lamp. I can bet the cord has a break in the insulation and is touching the metal in the lamp. Happened to me. Those lamps should be outlawed. the problem is that everyone who touches the side lamps turns them and this winds the cord up to a point where the cord breaks. You dont realize it because the cord is hidden in the lamp.
Get rid of it. I hope you didnt damage the Schecter

On most guitars/basses the bridge (and thus the strings) are grounded through the cord to the amp to the outlet (earth) ground. So one of his hands was touching the strings (ground), while the other grabbed the lamp which had 120VAC potential on it's metal exterior. Instant circuit through the body (including the heart). The current never touches the sensitive electronics in the amp or guitar, it goes straight to ground, and the human body provides enough resistance to keep the current from melting the cord and/or tripping the breaker.

1 amp of ac current is more than enough to kill a person. The body is a pretty good resistor so the voltage drop through the path to ground (in this case Brendanbass) will be pretty large. The grounded equipment wont see 110 volts and the current will probably be milliamps. Definitely serious stuff.
