I figured out that an outlet in my friend's music room wasn't properly grounded when I happened to touch the chassis of the rack mount, which surprisingly we had never touched while the amps were plugged in. It was only a tingling sensation like putting a 9v battery on your tongue. We plugged the power supply into a different outlet and that fixed the problem.

Turns out my amp was crap. Upgraded to a more premium one and bought a better cable, no issues. Thanks for this

[@hoosierdaddy2308]

I was jamming at a little little stage at a bar one time and I was shocked like you can't believe.. I stepped in a puddle of bear or something and man it grabbed me.. Another time I was shocked by touching the microphone stand.. I had an old Fender Twin reverb.. This amp didn't have a 3 prong plug and the building was about 110 years old and who knows how old the electrical wiring was.. I ended up getting active pickups so I wasn't grounding the strings and I bought a Nady wireless at the time.. I've never been shocked since.. I don't use old stuff now like the Fender twin which was stolen.. Even if I had an old amp I would get it fixed.. Scared me.. I hate being shocked.. Thanks so much for this..Very cool stuff..

[@RockG.o.d]

I feel very little shock like a 9v battery when i touch my guitar strings with my forearm. It doesn't matter what amp I use, its always the same, so I guess its normal for a little current.

Just happened to an artist I manage. Using a newer Fender amp and when mouth or hand touched the mic got shocked. Going to test the amp. Told the venue too so they can test on their end.

[@johnreardon4944]

I'm a live music venue owner in Japan. Before I opened last year, I had all of the wall outlets changed to accept three prong cords. The outlets are safety grounded. We have never had a shock problem until yesterday. I have a 1969 Fender Super Reverb from America with a step up transformer. The amp is 120V and has a three prong power cord. The step up transformer accepts the three prong cord, but the other end that goes into the 100V wall has only two prongs. We've been using the amp fine for one year and on the previous night too. So when the guitarist got shocked at sound check, we were surprised. We figured out that only this amp was the problem. My question is, why did unplugging the transformer from the wall, rotating the prongs, and reinserting it in the same outlet fix our problem? Did our amp have a buildup of static electricity? I will definitely buy a three prong transformer, but I want to know what the original problem was. I will test the amp with a voltmeter today as per your video. Thank you so much!

[@AudioUniversity]

I’m not certain, here. My guess is that the transformer removed the pathway to ground. A transformer creates a gap, removing the direct, wired connection. Search around on Google for how transformers work, and that might make what I’ve written here make more sense.

[@johnreardon4944]

@@AudioUniversity Thank you so much for the reply. I think you're right. I will start there. I have a decent understanding about transformers already so I get what you're saying. I'm a drummer so I don't mess with the amps much. I did, however, know that grounding is important hence I spent money to upgrade the outlets before I opened. Most old Japanese buildings only have the outlets for two prong plugs.

[@bartosik321]

The ground wire is just a safety meassure to provide a route for the current from the chassis to the neutral wire if a hot wire ever touches the chassis, this is not a normal situation and means that your electronic device is BROKEN, checking if the chassis is connected to the ground wire will not solve the problem and it is still dangerous if the situation described above ever occurs, there should absolutely never be any voltage on the chassis of the device, if there is, either open up the device and check for any disconnections or just toss that shit away

[@billpholde4816]

Good video. Here's what happened to me. I was getting shocked while holding my guitar while touching the string, amp on. It turned out to be an outlet. There's a green light on my power strip, when it'son, I'm grounded. I noticed it wasn't on. I wiggled the pluf, while it was in the wall outlet. The green light flickered on and off. The ground on the wall outlet is loose.

[@yeppieyay8906]

Good day, sir. I feel electricity whenever I play my electric guitar. I think I feel it when I touch the strings. My amp, which is a Boss Katana MK II, does not have a 3-pronged plug. What do you suggest be my next course of action? Could it possibly be a problem in my guitar too? How do you suggest to correctly identify the source of the problem?

[@AudioUniversity]

I had an old amplifier that didn't have a 3-pronged power plug. It was shocking me when I touched the guitar strings. I took it to a repair shop an they installed a 3-pronged power plug - the amp didn't shock me after that! I recommend you take your amp to get a 3-pronged power plug installed!

[@yeppieyay8906]

@@AudioUniversity My amp is relatively new and the model was only released last year. Do you think the amp really could be the problem? I also read that it is common practice for guitars to have groundings run current through the metal bridge and onto the strings to give off the excess electricity to the hands or body. When I touch mine, the electricity is very noticeable, sometimes even uncomfortable. Do you think this is safe?

[@girouxs0518]

Would you do the same continuity test for a mixer? I.e. input and ground prong?

[@AudioUniversity]

Yes. The ground on the power plug should be connected to the chassis of the mixer. Each input ground pin should be connected to the chassis. So there will be continuity between the input ground pins and the ground prong on the power plug. Good luck!

If the instrument cable didn’t do its part to provide a pathway to ground, it wouldn’t carry the guitar signal. In other words, if the cable works, it isn’t the cause of the shock. Have you tried playing your guitar in a different building to isolate the power circuitry in your house?

That amp runs 6 batteries 1.5V and is about 8Watts.

[@max6419]

[@joesolorzano3207]

Would a power conditioner solve the problem if it's the main power source? (power strip or wall outlets)

[@AudioUniversity]

The power conditioner would only solve the problem if it provides a pathway to ground that was not there without it. A power strip could help solve buzz issues by establishing a common ground reference to all of the connected devices. Plugging connected devices to different power sources can sometimes cause a ground loop, which results in a "buzz".

Are all three pronged plugs safe? My Audient Audio Interface came with a three pronged connecter but the third prong is made of plastic(probably for a better fit) while the other two are made of metal

The safety ground feature of a three-pronged plug is only possible with three metal prongs. While all amplifiers should have three prongs, most audio interfaces do not. I hope that helps! Thanks for watching and commenting, @Ishaan Kunwar!

The noise probably becomes quieter when you adjust the tone knob only because the upper harmonics of the buzz are being turned down. I would say it's worth taking the amp to a repair shop to see if they can find any shorted connections to the chassis. If the amp isn't the problem, you might test to see if the problem persists when connected to a different source of power (another building or another power circuit in your building).

i had a guitar amp and one time i got an electric shock from it and then nothing happened then I brought a new one it’s a good brand and this is happening to me rn

[@AudioUniversity]

Are you using any other electronic devices?

[@Alex-yl2fy]

Audio University no it wasn’t never mind thanks anyways i solved it

[@AudioUniversity]

If you don’t mind sharing how you solved it, it might help others with the same problem. Thanks!

[@devrictaylor8893]

I believe my problem lies in my outlets

[@TheNewenglandboys]

So electric guitars have been around since the early 50s when there were no 3rd prong plugs or outlets. How did the not get shocked?

[@AudioUniversity]

That's an interesting question! I'm not exactly sure, but I think they were designed to ground to the neutral pin of the power connector.

[@mrmeme-jq6qr]

I use microphone cover when this happens

[@theskullfedora8987]

...what if its a USB mic

[@AudioUniversity]

Same basic principles apply - a USB mic is just a microphone, preamp, and audio interface built into a single device. I’m not sure how USB grounds through your computer, but I believe it does.

[@pixy547]

If I use a three prong plug but uses a extension chord that can connect the 3 prong plug but the extension chord is only 2 prong and connects it to the wall plug is it still going to shock me or not?

[@AudioUniversity]

I would NOT recommend connecting a 3 prong plug to a 2 prong cable or adapter. This can be very dangerous.

[@pixy547]

@@AudioUniversity I'm using a fender champion 40. Someone said if it's true that I can use a power regulator or some sort or should I stick to 3 prong cable and socket? My only concern is that a fire could start or either killed by the amp

[@AudioUniversity]

While I’m not sure exactly why your getting shocked, I can certainly recommend that you only use a 3-prong connection to power.

[@noahbones1221]

My old amp has a ground, its not shocking me. The new amp isn’t grounded and shocks me.

[@AudioUniversity]

Maybe not what you'd expect! Have you had any luck fixing your amp?

[@noahbones1221]

@@AudioUniversity nope. Eould need to grt a grounded power supply or somehow ground the current one

[@AudioUniversity]

I had that done for my vintage tweed amp in the background. I used to get shocks when playing it. Replacing the power cable fixed the issue. It’s well worth it!

[@intermediate153]

I am using a fender mustang lt25 and I'm getting shocks from my bridge and strings when I put my arm on it(not the hand) my old vox amp came to me with a extention (idk what it was but it was something to control the voltage)the guy who i got it from told me it'll get expired quick if I dont plug it to that volt control thing... also... my amp remains on for 2 to 3 GOOD seconds after I switch it off... what to do?BTW its a three pronged plug

[@Ashriffic]

Oh im having the same problem with my lt25 did you find any solutions?

[@graygusher]

my arm feels like its getting shocked and also my thumb feels shocked too but i have a shitty amp so it would make sense

[@graygusher]

just figured it out my amp is plugged into an extension chord

[@AudioUniversity]

Glad you figured it out, @Graygushers!

[@anuvette]

I have a digital multimeter but i dunno how to use it and what im supposed to look for

[@AudioUniversity]

Beyond testing the equipment like I demonstrate in the video, I don’t know what to recommend. Sometimes the problem lies within the equipment, other times it is the result of another variable.

[@anuvette]

@@AudioUniversity I set it to that omega thing like you said and it showed "1" and when I put the needles like you did in the video, it stayed the same. I am guessing it was supposed to change? Is my amp faulty?

[@AudioUniversity]

Does it show a “1” when you touch the probes directly together?

[@anuvette]

@@AudioUniversity yes.. it does

[@AudioUniversity]

That means that there is “continuity” between the two probes. In other words, the circuit is closed. When testing the amplifier, you are testing to make sure the different parts of the amp are connected. So, if you see a “1” that’s good, because it indicates the probes are connected. Does that make sense?

[@rahulramesh100]

stop saving the crux of the video to the last 5 seconds.....

[@samuelmartin3640]

Bro idk if you could help if you still got time lol but fuckin A dude I turn on my amp and jam out for about half a hour and then I get a fucking shock either on my fingertip from the pickup or the bridge of the guitar shocks my palm it’s not like a crazy shock it’s enough for me to be worried I changed my amp cord for a new 3 prong and it still has the same issue could it be my guitar itself I’ve thought about maybe having to re solder the wires and etc
