OK. :D

Good thing you're not like these guys:

:D

I was joking with you. You're really insecure when it comes to your whole "nobody had gigged as much as me" thing, huh? We get it, Bob, you've gigged. We get it. :eek:

not insecure at all man ...... but generally when someone says something it's cause they don't believe me ..... I get that a lot.
So i explain myself ..... and even then I get a veiled insult ...... and in the context of this thread I was pointing that out to others that may not know.

I've never understood why, if someone takes the time to explain themselves it comes across as being mad or upset.
Sometimes it's just a further explanation and/or additional inmformation.
 
Actually if everyones so paranoid about electric shock risk, get an acoustic.

Possibility to be dead after AC accident will be much higher this way !!!
AC accidents happen:
A) Lethal AC voltage on chassis of your not grounded amp and touching grounded microphone or lighting equipment, or other grounded stage equipment with other hand.
B) In case grounded amp and touching not grounded microphone, or lighting equipment, or other stage equipment - what has 120, or 220, or 230, or 240, 400 V AC, etc. voltage on it.
Such situations happen relatively often !
About noise/hum:
Check your guitar's shielding and grounding.
Hum reduction this way means your guitar is not fully shielded, or not shielded at all.
It is the simplest method how to check guitar's shielding quality.
Fully shielded guitar has very minimal hum level (dependable just little bit of pickup orienting) and is not reacting on touching strings.
 
Lol....If I can get it DEAD silent....I want it DEAD silent.

Meanwhile, some of you guys are pretending that you can get a dead silent feed by shielding a guitar when there are other ways noise gets into a feed.

This was not mentioned as a stage solution where the odds of a deadly load reaching you are significantly higher.

The guitar is shielded AS WELL AS POSSIBLE. I built it and did everything possible to ground and shield it...and I'm an engineer having worked 20 years in aviation...so it's not like I can't understand electricity or the safety issues of a situation.

There is a near ZERO chance of getting a deadly shock through this studio rig. And it isn't voltage, it's AMPERAGE, that kills you, and yes, a tiny, dinky, minuscule, and very fricking small bit of amperage taking the wrong route CAN kill you...but you probably have higher odds of this happening walking around in your stupid house (built by the average construction worker) than I have taping this thing to my upper ribs on my left side.

Finally...anyone that wants to could rig up yank disconnect leaving one with virtually the same chance of deadly shock as simply touching the guitar.....you old women might feel better about that.

Lol...again.

Electrocution theories aside...yes, it IS possible to have a dead-silent rig without doing what you are doing.

That's not saying that there are never times when rigs can have some noise in them...but you're comment above implies that dead-silent is some kind of pretended hoax....huh?
I'm more surprised by the occasions when I do get some noise in my studio amp rigs....since most times I don't have any.
AFA live/stage...that's another thing, as you are always at the mercy of whatever electrical gremlins there are at a given location, but there's still ways to keep things quiet without the need to run wires down your pants. ;)
 
I don't really have a problem with excessive noise, but I think I'm going to try this anyway simply because it sounds like fun.

That's not what I said.

Dead silence is certainly possible outside of using something like this. If you were to wrap a building in about 30 layers of chicken wire and a truckload of tinfoil, leaving enough for a good hat, and then grounded THAT...there would be virtually no RF coming in from outside the studio. Then all you'd have to do it take care of the sources INSIDE your studio. My point is that RF is everywhere and the things that absorb it and stick it into your signal chain go well beyond the electronics cavity of a guitar.

My gear is all good but my studio isn't. I'm working on it now but I can't do anything more to the building to deal with RFI and EMI. It can be pretty expensive or pretty cheap to deal with problems. There certainly are other solutions. I just want easy ones. This is easy, it's cheap, it's simple...and I'm apparently risking death. I can live with that risk since that happened when I was born and it's pretty short odds I'm going to die of something else.

There's a lot to read on this....this is pretty well written and it backs the part I said about galvanic skin potential. Do the experiments at the end. All that noise is in your system...not mine. Then consider that there is no guitar attached during this experiment.

Mmmmm...got no chicken wire around my house, got no tinfoil, and I don't wear a hat (well, sometimes when it's cold outside)...and I don't have the RF issues you are describing. I also don't usually have ground issues, since I wired my studio properly...with the rare occasion when a single pedal/device upsets that grounding.

Also...RF interference is not ground noise.
I don't see how you grounding your guitar with a wire down your pants would have any effect on any RF that you were experiencing...unless your are also wrapping yourself, the guitar and amp in chicken wire and tinfoil, and attaching that to the ground wire in your pants...?
I like simple solutions like that. ;)

I'm not saying you've ever accidentally chewed a battery, Greg but I'm pretty sure who, between you and I, is more likely to get electrocuted.
Click to expand...

Well I got four big monster amps sitting right here in the room with me. I've never been electrocuted nor do I do stupid things like run wires down my pants. And there's no noise except for the noise I make, so I'm doing at least that much better than you.

I'm not on the internet while I'm not being electrocuted by my guitars and amps that don't make any noises that I don't direct them to make.

Well then...you can't benefit from it.

Do you ever ask yourself, "Hey Greggy...why are we in this thread"?

I don't. I know why you're in it.

I'm in lots of threads. This is a message board. I'm in this one to point out it's stupidity. You see, it's a stupid thread outlining a stupid "solution" to a stupid problem. Instead of smartly fixing the stupid problem, you propose a stupid band-aid workaround. It's stupid.
 
I've been zapped by an amp through my guitar. :eek:

Yup. I was probably 14 or 15 yrs old. A friend gave me two 12" Celestions, so I built a cabinet for them. A big one. It was cool.

Then I used an old PA amp. This one:

Bogen PA.webp

I had to find an adaptor from 1/4 to screw-on, but Radio Shack had them back in those days. The PA amp was so old, it had a 2-conductor power cable and both spades looked the same. Got everything hooked up down in the basement. Kicked off my shoes for some real jams, plugged in the guitar, turned the power on......

... and it tingled. :laughings: Tingled pretty damn good. :facepalm:
 
To tell the truth...on the occasions when I do get some noise, unless it's so extreme that it is obviously bleeding OVER the sound of the actual guitar playing....I don't even bother with it.

It's Rock-n-Roll....and not a string ensemble performance.

Like with single coils...I just spin/move around until I find the spot in the studio where it's "minimal"...and then play on.
Plus....any ground noise is eliminated 99.99% of the time as soon as you touch/play the strings, and with your right palm on the bridge, where it is 99.99% of the time when I play.

Here's a better option for you instead of down your pants:

Yup. Single coil . . . If I'm facing computer I get noise. Spin around 90 degrees and I get no noise.

I'm never overly concerned about noise. I like musical noises: finger squeaks on strings, bass pedals creaking, upright bass string buzz, breathing noises on wind instruments . . . and the noises of amps. They are all noises that attest to the human-ness of the performance.
