3) Try and use grounded outlets, and have the same ground. Bring your own surge protector/power strip everywhere you bring your amp. It will reduce noise and you will be your bands hero (everyones always looking for a place to plug in).
Things to remember about AC current:
Bring an outlet tester with you to every gig.
These babys can save you from having the shit shocked out of you. They only cost as much as a two sets of super slinky's.
An often overlooked source of 60z hum comes from the Neutral line being too small. As far as Natinal Electrical Code goes ( I have the 93', 96', 99', 02', and 05' copies of the NEC book at my day job) there isn't much you can do. So long as the Neutral is sized to the breaker on the Hot leg, it's 'Code'.
What that means for us guitar players is that the harmonics from the transformers in all beer signs, dimmer switches, dimmer packs, refridgeration motors, the transformers in the power amps of our P.A. racks and all those lovley wall-warts will make their way to our guitar amps.
Over-sizing the wire from the panel helps, but that is something that has to be done while the place is still under construction.
If/when you test an outlet and it comes up as 'bad', don't use it. Run an extension cord 50' to the back of the room if you have to. It may seem weird, but at least you will live to tell about it.
Under the right conditions 7 1/2 watts is all it takes to leave you brain-dead. Lesser amounts can stop your heart, cause you to fill your pants and/or give you a pulled muscle or two. In the USA that outlet you plug into is rated at 1875 watts.
Club owners are notorious for having hung-over wino's wire the stage to work off their bar-tab, so don't even dream about offering to fix it.
You have no idea what lies behind that recepticle.
You could be opening a pandoras box of even greater problems!
If you 'fix' it and somebody gets hurt, or your 'fix' fucks-up something else you could end up in court.
It just ain't worth it.
I have a friend who ran sound at a local club call me to 'look' at their situation once.
People were getting shocked on a regular basis when they sang, when the dimmers were SWITCHED off, the lights would glow.
Some moron wired the 'stinger leg' from the 3-phase to half of the stage outletls. This problem went clear back to the breaker panel.
The only way I could convince the owner to act responsibly was to remind him that he could get his ass $ued if somebody went to a hospital because of his neglegence.
