What? You Don't LIKE Ground Noise?

We've gone a teeensy bit over the top...just like a teeensy Kodiak bear.

But you did sidestep the question about being preggers...

The funny thing is, I've been bloated on off for months now and was just reading an article on what may cause it. I take a baby Aspirin a day and they say that can cause bloating. It's not serious or painful and it comes and goes, but I feel pregnant today. It's the funniest thing you'll ever see when it happens. A guy with a 6 pack but also a bloated stomach. It's kind of weird.

Hey, if we're going to hijack the thread, might as well do it in style. :D

I think you're ready for Midol instead of aspirin....

There is no risk, the potential of the earth to the body through the suggested wire to the skin is exactly the same as the earth potential through the fingers when you touch the strings. There is no extra risk. The risk you are talking about is if the amp has incorrect earthing you will get a shock, if this is the case you will get the shock as soon as you touch the guitar or if you are touching the guitar and then touch a mic that is connected to a mixer that is correctly earthed (as has happened to me in live gig situations due to the PA company not having correct earthing in the power supply, Ouch!).

Don't quote me on the math, but it's easier to let go of a string that starts shocking you than your pants.

It sounds like the original suggestion was doing this in the studio anyway. If your studio isn't properly grounded, you've got bigger problems than guitar buzz. (And live, you solve both problems with a wireless)
 
Things go wrong in the world. I wouldn't wire myself to anything unless there was at least a 1 megohm resistor in the path. (standard practice for ESD wrist and foot straps in the electronics manufacturing world)
 
You are already wired as soon as you touch the guitar. The ground is connected through the shield on the guitar cable to the strings.

Yes...and not everyone always touches the strings when the play. Intermittent contact can easily wreck a take. Also the skin of your fingertips doesn't conduct as well as other types of skin. I'm suggesting that it's a constant and qualitatively better ground.

True. I guess I just thought the subtlety might be lost on those that aren't aware that everything is about me taking a leak.

I think the real issue is when you're ever going to pass along a track of you taking a leak, so we can all use it in our songs, now that I've figured out this bit of wisdom.

And all along you've been telling us all about panning and reverb and other clearly irrelevant things, and I think of all the time I've wasted not thinking about you taking a leak.

Now that I understand, I can take things in a different light. Everytime I think I have it all figured out, there's always SOMETHING I didn't think of...

I'm sure it works....but you're over-thinking it.

Like I said....I tried the wire thing once (I actually had it going to my foot, keeping the wire out of my way and stable under my foot)...and it worked, but after that one time, I decided it was kinda dumb and unnecessary since really, there's a very rare instance that my right had was going to at some point be "floating" over the strings and also NOT touching the bridge at the base of the wrist.
I've never wrecked a take because of any "intermittent contact".

Again...if you have that much issue with ground noise with your amps/pedals....there's more to that than just sticking a wire down your pants. ;)
 
In case of electric shock situation (touching something under voltage around you) - possibility to be dead will be some 5 time higher because you are stable grounded.
Hum in case removing hands from strings means just one - your guitar is not good enough shielded, or not shielded at all, it is the simplest check of shielding quality.
Touching grounded strings you become additional shield reducing hum ;)
In case of right shielded guitar there is no hum dependance touching strings, guitar must be quiet.
 
Here in the UK the notion of putting a grounding pad on a person who is likely to be exposed to fault conditions is going to result in a safety test fail, and is frankly plain stupid. Death usually comes from the shock current entering at one point, crossing the heart and exiting somewhere else. Current has to flow, and not much of it! Touching a mic with your lips and having it pass through your chest to the metal plate is asking for trouble. In fact, in sensitive soldering stations, workers use a wrist band to ground themselves to stop static build up, but most use their working arm wrist, so if they accidentally touch supply voltage, it exits without leaving the arm. The unpleasant experience many of have had from valve amps where half supply voltage gets put on the chassis in a fault condition means that this stupid and dangerous idea shouldn't be considered. Since the first electric guitars arrived, hums and noises were an everyday unwanted feature, and if you can't screen or modify the guitar, most simply develop the technique to keep a part of your body on the metalwork. If for some reason you need to take both hands off, then making sure the jack socket on the amp is properly grounded usually does the trick. Potentially noisy guitars plugged into ungrounded amps is your own decision. Grounding your body is frankly suicidal, and no doubt in the USA a call up the lawyers scenario!

Some people think grounding is some kind of magic, it's not! It just creates a path extending the ground upwards. Your body has no place in that circuit at all. Remember that electricity linesmen can hang off a live cable with no ill effect, but adding a ground is spectacular and short lived.
 
Other fixes

Agreed - grounded to your amp does not mean the other power sources are in the same phase so touching that mic can be exciting

Other choices: diagnostic
Why is your guitar noisy?
Probable - the posts are not grounded
Test - without touching strings or guitar ground listen to the hum and then touch the post (only the post) of your beast

If the noise gets louder the posts are not connected to ground. Better to connect those posts to ground than your body for a variety of reasons.
Don't know how? Several methods work but how well is based on pickup style

Fix the guitar before wiring yourself up.
Wild Mike had his heart restarted last summer.
HG wasn't so lucky in the fall

Don't trust anybody's power supply
