I'm proud to present the Flawed Logic Fuzz MKII.
The original Flawed Logic Fuzz was a fun circuit, but it suffered from too short sustain and the modulation part could have been better. The MKII is improved in these areas and also has a couple of new features such as a depth control and a waveshape switch for the LFO. I'm especially happy with the new triangle LFO waveshape that makes a sort of phaser'ish sound.
This circuit is made up of a square wave fuzz followed by two gated oscillators in series (NAND gates). The LFO modulates the frequency of the second oscillator. This produces a very synthy, throaty sound that is unlike any other fuzz. I hope you like it. :)
