Clean up your guitar signal for 15 bucks - Harley Benton Groundbox 

Thank you

Mines a B flat

Hate to be a know it all but 50hz is roughly a G and 60hz is between Bb and B.

@@TheGuitarGeek We live & learn! 😉

You're right, it'll do the same. I used that "hack" on my pedalboard for a long time and still have a "ground only" main plug with the cable ending in a little plain copper wire that I can, say, fix under a pedal jack's screw. Works a treat. From all I gather, the reason why this works so well, is that it adds solid ground to otherwise weak arrangements of pedals and what not, hence any shielding works better. I mean, when you power up a pedal board with the usual suspects (aka PSAs or batteries), there's no solid ground connection others than the output running into the target (usually an amp). Make that a battery amp (as in this video) and you're completely doomed already (no solid ground anywhere anymore), but also things such as modeler setups (often running into DI boxes) often are a victim. Needless to say, it doesn't even work remotely as well when using wireless systems, but one should avoid those as the plague whenever possible anyway.

They have several uses. In high gain situations, dirt pedals, you raise the signal, and the noise floor, electro magnetic interference as well. This is usually quieter than your guitar signal. As your strings ring out and fade, the signal and noise is gated, shut off.

Earth has to be connected somewhere

@@TheGuitarGeek but this is for ground not earth.

@@jrr832 Same thing... Semantics, don't be a smartass

thank you!

Hi Simon. Are you an electrical engineer?

I know a fair bit about electrics, and also spend a fair bit of time on the Sound on Sound forum where grounding issues come up fairly regularly.

Thanks for being clear

As I said, this product has its place, and I believe there are similar products with a ground wire to a mains plug with a crocodile clip on the end that can be used for attaching to the metal casings of jack plugs or XLRs to provide a ground reference for laptop-based recording systems where there is no ground and everything is 'floating'. But by curing hum by connecting a good ground to the shield of a guitar lead just proves that the cable shield isn't grounded. But with a mains-powered amp set-up, it certainly should be. If it was grounded with a good low-resistance path to ground (less than 1 ohm or better), then grounding it again won't improve anything. So it's very likely that if it does cure hum on a mains amp, then there's definitely a dodgy or missing ground connection somewhere in the system. With a battery amp or a set-up that's powered from double-insulated PSUs, then its certainly likely that there won't be a ground connection and hum can occur, but the system is electrically safe. This should be the only type of set-up where this grounding plug should be used.

Thanks again. Just be careful about giving out such advice when knowledge is not based on being fully qualified to do so.

Amen!

I don’t think the Joyo device is at all similar, if it’s that dongle which sits in line with the power to the pedals. That's a filter, not an earth line.

@@themellonfactory My mistake. I don’t know enough about electronics.

So annoying

Well that's why 60 cycle hum sucks, man!

Yeah I hate those guys

it's 10 better. or 10 worse...

Discontinued 😞

Use a metal bodied jack cable in your rig. Connect a long wire to the ground pin of a mains plug. Connect a crocodile jack to the other end of the wire, clip it to the jack body.

battery powered amps don't have ground hum. batteries are DC not AC. i guess he uses the katana mini with a power supply. correct me if i'm wrong.

Believe thats the Antigua Squier baritone jazzmaster.

@@aliensexist15 Thanks! I'll seek and hopefully find! :)

I know and you didn’t even make it to the end.

Said the kettle to the pot 😂

At least he did not compose a 6 minute intro song with 4 MacMulls and 5 boutique amps. Sorry for that 🤣🤬 animals at the end 🐛🐞

@@hawedehre 6 minutes? Felt like an hour

@@backlom ​ Hahahaha can you believe it? 60 Cycle hum sucks. And F.U. Glenn... oh, wrong youtuber sorry...

If there’s voltage on your household ground your ground is not grounded and your house is a death trap.

There shouldn't normally be voltage on your mains earth. Look at your earth as a safety valve. It should be a better route to earth or zero potential than you. It should help prevent electric shock and fire in faulty appliances. Neutral or positive are constantly flipping or alternating currents. They are live, they should only connect to earth in the event of a fault.

Ground is earth

It has to be a small signal transformer inside. That will allow the signal to be passed but still isolate the earths (grounds) from each other.

It’s probably hardly worth dignifying with the word 'circuit' - in all likelihood it just taps the signal earth to an earth wire connected to the plug earth. I make my own with just a plug, a wire and a croc clip which I fix to the body of a jack plug.

I'm pretty sure this just connects the guitar signal ground to electrical earth. The jacks will be connected to each other.

woohoooo

It’s also possible to create a ground loop with this. So I would not advise having it always plugged in.

Well you could put a us plug on it it would work just as well

@@TheGuitarGeek i didn't know if it would fit right. Ill check that out.

Who?

@@TheGuitarGeek hahahahahahahahahahahahahahah! Sixty Cycle Hum sucks.

I think it would be fine anywhere but the best way would be to try both methods and see which works best for you

@@TheGuitarGeek Thanks mate! 🤘

You could just wire a US plug to it.

@@TheGuitarGeek Pfff you say that as if I have any amount of practical knowledge or skills to my name.... xD

Hey, sure if that solves the problem you’re having

I hate that annoying noise.

I know. I’ve tried charging my iPhone in the US

I don’t think it would fix that but it’s a cheap way to experiment

@@TheGuitarGeek Yeah for 15 euros I think I'm just gonna throw it into my next Thomann order!

If you have no earthed sockets then your wiring is faulty and this will do nothing. Buy a simple mains socket tester, around £10. This will show you if the sockets are dangerous. All electrical sockets need to be earthed. This is to help prevent electric shock and electrical fires in the event of a faulty appliance. Get it fixed immediately.

That signal has to go somewhere. The socket will need to be grounded

@@TheGuitarGeek thought as much, thanks for clarifying; guess I'll go back to harrassing the land lord until he bloody fix grounded sockets in my apartment 😬

No hate for Steve

of course! The only way to know is to test it yourself

Nothing weird about it...

Most amps are grounded, this tackles a different problem...

Ryan who?

@@TheGuitarGeek 🤣💜✌🖖

Yup 👍

Thanks Andy I’ll definitely have to get one

Great news!

It’s not going to fix your house. Nope

Cause fish is the easiest way to get your recommended amount of micro plastics... wait you said tunner not tuna sorry.

I’m wondering the same thing

Well... yeah

One would hope that all wall sockets are grounded. The ground serves one main purpose. To take errant current safely away. Either from your body to prevent electric shock or shorting which may cause a fire.

That's a trick Europeans learnt from US suppliers

Cable brothers !

Achievement Unlocked! :D

Ooooh

It’s about time
