Danelectro’s president, Steve Ridinger, got his start in the 70’s by manufacturing the fOXX Tone Machine, the now coveted octave fuzz sound used by players like Peter Frampton, Adrian Belew, and Beck. The 3699 fUZZ is a faithful recreation, and a tribute (“3699” spells out “FOXX” on the telephone keypad, and that was the last 4 digits of the company phone number back in the day).
