Dweezil Zappa

what did Frank use to create this track?  I have owned a Subdecay Proteus for many years and it comes close but doesn't nail it.  Such a wonderful track from the Shut Up releases, by far my favorite from the trio.  It is such a guttural sound of guitar emotion. Beautiful- it has anger, reflection and playfulness all in one.

 Also, was it recorded w/ the Les Paul?
