Trace Elliot phones home
Can some one please tell me in plain English what an Earth lift is used for. My Trace Elliot Acoustic amp. has an earth lift switch on the back and I do not know what to set it to. I only have two choices and Ive owned this amp for 5 years now but I still do not know what this switch is used for!!
Thank you to anyone who can help.

That switch has long been a feature of guitar amps as a misguided 'solution' to humming. What it does, is opens ('lifts') the connection to Protective Earth (called Safety Ground in North America).
In other words, it addresses the problem of ground loop noise by removing the ground connection of your amp. This may reduce the hum, but it will definiteley put your life at risk, if you are plugged into bad AC wiring.
Set it to connect your chassis to Protective Earth, and then leave it there! Safety Codes on both sides of the pond have been updated to make this switch illegal for new manufacture.
