From teh Colorsound site:
So . . . I'm at Dick Denneys bungalow about 5 years or so ago . For those of you who don't know , Dick designed the Vox AC30 and was just about the best guy who ever worked in the music industry ! Well , we're sitting down talking valve echo when he produces a circuit board he designed back in 1961 . . . . It was still in his drawer ! We plugged it in and it blew me away ! it sounded FANTASTIC - like a germanium pedal - nasty - garagey - trashy - with ONE control that did everything at the same time - gain , volume , nastiness , garaginess ! We went into production straight away and called it the one knob fuzz . This is our latest version - it still it Dicks design but on a tonebender board and with one special addition - inside there's a little preset wheel that allows you to balance the effected sound against your true bypassed sound - sneaky eh , a one knob fuzz with a secret wheel ! ? So here's a trubute to the man himself , Dick Denney - king of the capacitors !
