I like the story behind this one. With this much acid that mask machine will talk.

It's amazing what people will pay for American culture. One of those McIntosh amps went for $378,000. I had one of those old SS amps and it sounded like the voice was coming out of a basketball sized hole in the singers chest cavity.
