And does Bon Jovi use it in songs such as Livin' On a Prayer? B/c is sounds like it.
It is called a talk box, the company heil makes the original one that peter frampton used in the 70's, it is a pain to hook up. there is a fairly newer one on the market called a banshee talk box, basically there is a speaker in the box on the floor it puts out your guitar up thru the plastic tube, when you put your mouth on it. you can manipulate the sound and it is picked up by the microphone.
