I borrowed a friend's foot pedal in the late 1980's and had great fun. In later years I think it was the Roland SE70/SE50 half rack effect "box" that had a preset which vaquely emulated it but it was rather limiting in its use as I soon got bored with getting my guitar to say "hullo" and other stupid phrases based on vowels!! as our band's song list didn't need really warrant the effect and so I was soon banned from using it.
It goes without saying that I didn't sound like the aforementioned guitarists.
