More than just distortion, sustain. To be able to hold a note infinitely it felt.
The left switch on the VOX pedal gave you that sustaining power.
So Cal bands: Iron Butterfly, Children of the Mushroom and Spirit were those that clearly stood out with its sound.
Dunlop's pedal was Jimi Hendrix, Robert Fripp to name a few's favorite
fuzz.
Then came the sustaining 'E-Bow', a hand held device that plays upon the pick-ups' magnets and steel strings.
I was re-inspired.
The first I heard its effect was on the strings of Steve Hackett's guitar on Genesis' 'Carpet Crawler'.
Applied live on Bill Nelson's Be Bop Deluxe guitar...
I had to have one.
Still do.
Wish I still had my VOX Super Beatle and pedal.
