how exactly does the talk box work. and where would I be able to get one?
I reckon it'd be fun to experiment with, and if I'm doing Bon Jovi covers it'll be useful, as the great Sambora uses it alot, with great effect.

Oh yeah, and check out how Eddie Van Halen makes his guitar sound like a chain-saw at the start of Poundcake.

A Double-Decker style Drill.
