Safety Issue my bottom.

I Discovered this from a local forum.Shocking!!
The essay Below are and as written by him(That other Tech in Cheras).

Enjoy

----------------------------------------------------------------------------------------------------
List of Famous musician been electrocuted :
Keith Richards- Rolling Stone(Unconcious on stage)
John Rostill - The Shadows (died 1973)
Les Harvey - Stone the Crows(died 1973)
Keith Relf - Yardbirds (died 1976)

Ace Frehley – KISS ( unconscious)
Michael Lembu besar- Satu Malaysia ( died while try to eat a electric guitar ^^ LOL )


Do you know a guitar is always having potential high risk when most of the manufacturer shield the ground wire direct to guitar bridge? so that when you are playing the steel strings, YOU are the one who be the FINAL GROUND of the whole wiring circuit!!

This is why we need to do COPPER SHIELDING with PROPER WIRING CIRCUIT( to isolate the bridge )!!
Here we can probably save your life!!!

Upgrade the safety level you guitar to XXXXXX XXXXXXXX NOW
Advantage :
Minimize the risk, Less Hum, More clarity sound!


Why other guitar including many famous brand guitar want to shield the ground wire to bridge? Don't they know the risk?
Of course they know, but due to the high cost of using copper foil and the labour , time.... they are common using a black carbon conductive paint for internal cavity shielding, but the effect is less than 30% if compare to copper.
The point is, it won't really conduct a good shield, but it is pretty easy and fast work for a factory which produce more than 200 guitars a day.
We offer FREE safety check for your guitar electronic in XXXXXX XXXXXXXX!!!
Come now!!!

Yustech now counter argue his point as written below

Enjoy.

I would agree shielding your guitar with copper foil does reduce a bit of noise and adds clarity.I strongly recommend this.
But as for the safety issue,it a case of believing everything he reads from a US guitar site.

I was even lead to the site by this Tech.Before I give my personal "not taken from any site" views,lets learn some Electrics,Metallurgy,Electronics,Components,General knowledge and a bit of common sense.

Electrics
First of all looking at the year those guitarist died,in America safety issue was taken lightly compared to us here where Grounded(3 pinned plug) is a must.Thanks to the British for this.


Metallurgy
As we know copper conduct electricity very well, if there's a big load and you are on the receiving end,I smell me burning.haha


Electronic.
all circuit need ground to work properly,its the way it is.Cut that black wire connected to the spring claw and you'll know what I mean.


Component.
Put in a cap in between the claw and black wire.,further more a 400v cap in your guitar?.Its as if 240v isn't enough to kill you,450v will.haha..put it in then.


General knowledge
Most solid state guitar amps has protection component(Fuses),Grounded chassis and most does use 3 prong plug..All the components work below 20V at the preamp section and a bit higher at the power amps.In a case of voltage burst or leakage the components will die/blown first or fuse will blow before the lethal voltage gets to you.


Common sense.(My Favorite and The Solution,If you're so concern about safety)
Put in 100/250mA fuse between the Hot wire and another for the Ground.If I were the Guitar Tech for them in the 70's,those fella would have survive another gig.


My assumption.

The earlier claim by the other Tech is False,Dumb and Stupid.haha..a good way to put fear and make money at the same time.Myth busted?? I believe so but hey!, don't believe everything you read here and I very much believe shielding has nothing to do with saving your life.

What do I know,I'm just That Guitar Tech & Tutor in Greater KD.Telling it as I see or read it.

I know shit when I see one,This one stink and have a nice smell.Haha
