Excellent job talking about safety and noise ... something worth sharing.

Except for one part towards the one fifth point.

Most of those screws nowadays in the middle of that duplex or quad screws into a plastic electrical box, or.
Or somebody has replaced part or all the plumbing in plastic, and so the path to ground, from that steel electrical box to nearby plumbing, is of no use, because when that segment of plumbing is changed out to plastic the path is broken.

I'd recommend a better circuit tester than those, but they're way better than most of us use, and they'll usually show you that screw onto which the adapter is being attached screws into something other than a good ground. Worse, sometimes those three prong type outlets aren't actually providing a ground or the leads are reversed.

But the Taylor man is definitely sending us in the right direction. No, I am not a trained electrician.

Thanks. I found it informative.

That's a good video.

I use one of those Furman rack mount power conditioners too. It insures that everything is grounded (provided the house wiring is correct) and also cleans up any irregularities in the current so that I am feeding my baby a nice, clean sine wave.... I think the one I have was about $35 bucks new from Musicians Friend

I use one of their pedal boards too for the same reason. I've had pedals get fried, or at least lost all of my presets, from spikes and drops in the house current. That can happen when a big load is added to the same circuit you are on, like a heavy duty dishwasher in the back or a large AC unit or something and it kicks on suddenly while you are playing. You'd be surprised, or maybe not, where some stage power circuits get tapped in from. Some of these older places or outdoor venues have never heard of an Electrical Inspector so it's best to arm yourself with a little knowledge and protect yourself against any problems that you will likely see.

A guy I know has a rack mount unit that displays the actual line voltage in real time. I've sat there and watched it go from 80 all the way up to the 150's while the band was playing at an older club. Not good! Especially in this day of PC boards (not that anybody on the TDPRI would use anything that wasn't all tube!) I try to treat my musical gear the same way I treat my computer gear. After all, I've got a lot more invested in it.

Good video. Very basic and very good. Thanks.

Computer stores carry small surge protectors made for laptops that run about twenty bucks. They aren't power conditioners, but THEORETICALLY if I had one of those digital signal processing things next to my 30-watt class A I would definitely want to protect the computer circuitry.

I'm finding it remarkable that you have AC outlets and extension leads in the US that aren't earthed. Every power point, extension lead, power strip etc down here has to comply to Aust. Standards and be earthed. Seems like a recipe for disaster to take the earth lug off ?
