Variac, used to "brown out" a dimed roaring 100 Watt Marshall Superlead tube amplifier (ala classic Van Halen) by lowering the voltage thus reducing volume. My EVH tone chasing days are over now due to injury so don't need this anymore. Can also be used for its intended purpose as an electronics testing tool.....LOL
I had to drive up to Phoenix to buy this Variac new a couple years ago.
I'm asking $50 cash.
