The 3699 Fuzz is a faithful recreation, and a tribute of the vintage FOXX Tone Machine of the 1970s (“3699” spells out “FOXX” on the telephone keypad, and that was the last 4 digits of the company phone number back in the day). The originals today sell for over $600, but this features the same circuit with some improvements: the octave can be turned no and off through the right footswitch, and there’s a mid-boost toggle switch that allows you to remove the mid-cut of the original.
