Fellas, if somebody can share some knowledge about this...
In 1977 I bought a sound effect somewhere in LA, called the Hawk III. It was not a foot pedal. You had to strap it to your waist belt. It required two 9 volt batteries and had 3 switches and 2 slide knobs. It gave me a sound like Chris Squire in "Yours is no disgrace" when I played thru my Ampeg B15 with 2 nice and big cabinets. Somebody borrowed it and stepped on it and broke it

. I could never find another one, guess the company that made it is lost in the mist of times. I have never sounded like that again. Somebody know anything about it? Thanks in advance.
