The Kaiburr Fuzz is a fuzz designed with the Rhythm guitarist in mind. The controls for Fuzz and Gain give you a wide range of controls over the shape of the distortion the circuit produces. It can go from a low to mid gain overdrive (with the fuzz dialed back) to a full on vintage style wooly sound.
The circuit, though not overly complicated, is an original design that employs Darlington and JFET transistors. There are not clipping diodes-- all the distortion is from the transistors slamming into each other and the power rails. The Darlington input makes the fuzz pretty responsive to guitar volume controls (though not as sensitive as a germanium circuit) but it can also be placed later in your signal chain without changing the character of the sound too drastically.
The Glitch control features a 3 way toggle switch for High/Off/Low settings on a unique "Spike Tooth" tremolo feature, while the knob controls the rate of the effect. When the Glitch control is switched on, the LED near the hilt of the sword blinks faintly in synchronicity with the rate of the effect.
