Electricity in string

[wishforbass]

Again a problem started .
I was playing with my fender rumble 100 amp +my passive bass .
In middle I felt my string burn my hand ,I touched the string but nothing happened but when I rest my hand slolwy on strong i felt burning on my skin .
By slight touch the electrical bite felt .


The amp is new so I cang understand why Something like this happen or don't know is it amp problem or bass problem.
Need help because the bite feeling is so annoying and painful.


The amp has repair card so j can send it for repair but how can I find it's amp or bass problem ?
What should I do ?

make sure the electrical outlet you're using is grounded
if you have a multimeter, check voltage between the live side & the ground terminal
you should get 230 volts
on the neutral to ground side you should get a very low voltage, maybe around 4
if you're using an ungrounded outlet, stop!

What is the best grounded electrical outlet for metal?

Barefoot on a concrete floor by any chance?

Barefoot on a concrete floor by any chance?

Yes ,
Because it's folk music and the design is just foot

But even with that shouldn't amp manufacturer kind of design amp the way this thing not happen ?!

before I got the ground sorted in my humble abode in Thailand, I'd wear rubber flip-flops in the house
I finally got it fixed, but it took three separate ground rods tied together.

Make sure the amp is grounded. Take it to a tech if you need to. You should never get a shock from your instrument. This can be fatal sometimes. Whatever you do, don't touch your lips to a microphone while holding your strings until you get it sorted out.

Opened and check instrument .it seems that don't have any problem for amp I don't have knowledge and I'm not enough brave to open it and check it .but I will show it to a local tech and if needed send it to manufacture for fixing .


Still can't find the problem specially that most things look normal and ok .

It's either a faulty power source or a short in the amp. The instrument is charged by the short circuit in the source or the amp. Ground only adds safety in case something is wrong and the power source or the amp has a short. Not the bass. This is exceedingly dangerous. Don't screw around.

Yup, time for the professionals to take over. If you don't know exactly what you're doing, stop playing and get the amp looked at. You may also need an electrician to check out your home's wiring. As others have already said - but it bears repeating - this is nothing to screw with or take lightly. This could be deadly.

I think I should add my country outlets doesn't have 3 wire .it has two mean no ground at all available .
So I should fix it the way that can make it work same time with no ground .

Iran has type C and F which are two wire and three wire respectively. It sounds like type C is what is available in this case. If converting the wall outlet and power cable to type F is possible then I highly recommend it. But I don't expect that to be the case.

Alternatively I would suggest wearing shoes that do not conduct electricity. Another option is to get a wireless kit if at all possible so the bass does not have a wired connection to the amp.

Absolutely make sure you don't touch your lips to a microphone while playing. If you do need to sing into a microphone I highly recommend a foam wind screen to isolate you from the metal part of the mic. Also don't touch the microphone with your hand when your other hand is touching the bass.

Can you imagine him using that grounding device mentioned in last weeks post that gets rid of hum by attaching the metal plate against the skin under the belt! Something to think about for those that said it was no risk with modern amps.

This sounds like and improperly grounded receptacle. In the US most big box and most small hardware stores sell a yellow plug in receptacle tester that lights up to tell you whether the receptacle is properly wired and grounded. It wouldn't be the 1st time a receptacle was improperly wired or missing a ground. I would like to think this are available for 230 volt receptacles where you are located. This sounds like either the receptacle or the amp have a missing or loose ground connection. STOP using until you are sure.

Unless you have the correct electrical test equipment and knowledge of how to use it I would seek professional advice. Have the amp tested for electrical safety first, 5 minute job.

Sounds like you almost had a case for changing your user name!

 

[Off-Beat]

Do you have any electrical knowledge and equipment?

 

[Gasman]

Stop. This is dangerous. Don't play it. Get it checked out by a professional.

 

[johnson79]

I'm thinking the issue isn't necessarily the amp, and more likely your receptacle.
And it has nothing to do with the fact that you're in Iran. There are plenty of incorrectly wired receptacles all over the globe... I'd have that checked out, can be dangerous.
