I don't know the slang term for a guitar but the slang term for playing the guitar is "shredding the gnar" so I'd imagine that the slang term is gnar.
I'm sure there are more than a few, but I've always been partial to "axe man".
"shreds" maybe? or my personal favorite "molests the fretboard" hope this helps - Kyse
