That's right. For "Black Dog," Andy Jonhs used two Universal Audio 1176 Compressors in series. One had all the compression buttons punched out, so it functioned like an amp, and that signal slammed the mic input in the mixing board, causing the mic amp to distort. It's a cool sound with a very unique character.
