Is there a "latex fetish" forum around here?hrn said:...and if I wear rubber gloves while playing...
hrn said:Thanks guys,
Yes, it's a terrible hum/noise problem. Just trying to find an easy way around it. If I use guitar cables with earth connected at only one side (signal end) would it be so very dangerous then? It's very common with wall plugs here without any earth on them.
Would it be harmful for a Marshall amp do you think? I do it very often with a solid state bass amp getting it dead silent from hum and noise.

I have an old silverface Bassman (70s era, AB165 I believe). I bought it second hand, and the original power cord had been replaced with a three-prong plug, with the ground wire soldered to the amp chassis. The amp has a switch on the back marked "Ground", which I would presume is a ground lift, but it has no other indications. When the switch is flipped to one direction, it works fine. When it is switched the other way, it immediately pops the circuit breaker.
What's going on here? Does it sound like something is shorted? Is this simply caused by the amp being chassis grounded?
Here's a picture for those who aren't familiar (this isn't of my amp, just a picture I found on the Internet):

I agree, but high-voltage can be low current. Ever get zapped by a faulty spark-plug wire on a car? Thats several thousand volts, but very low amperage, so it hurts like a motherfucker but won't kill you.MCI2424 said:Current can't exist without voltage. No voltage, no current.

Yup. It sucked, but still didn't kill me.ggunn said:Ever get zapped by a spark plug wire while leaning with your crotchal area in contact with the body of the car?
