Square to triangle wave conversion
I have been mulling over the idea of a fuzz pedal that would create(convert) other waveforms besides a square wave, most notably triangle and sawtooth. Has anyone done an experiment such as this before? I was thinking maybe an integrator circuit using a single op amp to get the triangle conversion. I have seen a few circuits for sawtooth conversion but, not many(really none) in regards to the triangle waveform. Any thoughts/ideas would be much appreciated.
By the way, I am new here so hello to all!

Urr? Maybe you are confusing the the square wave of a distorted audio signal which contains many frequencies with the triangle/square waveform of a fixed freq LF oscillator which is used as a control voltage for things like Vibrato. There is a big difference.

You could try checking out some of the circuits on this website:

Thanks! I have come to the realization that a triangle wave is not going to be the cheap,easy fix I was looking for. I am quite familiar with SSWSMS circuit and a good deal of inspiration came from it. It seems the likely solution is to stick with a more simplistic circuit such as the SSWSMS.

You could use an integrator (an active low-pass filter without DC feedback). Though higher frequencies will create quieter outputs and lower frequencies might clip. Worth a try though!
