Fuzz audio converter using LM324

This is Fuzz audio converter circuit. By use diode 2 pcs. in feedback circuit of OP-AMP IC , number LM324. I make for build way music sound that have unusual character. By limit output voltage , give a hand net between 0.7Vp-p waves square signal that is the result that is will proportionate big compose harmonic be the odd number , resemble the sound of a donkey. The Resistor at use fine the depth of fuzz audio. It will use fine the level that want to is born top waves slitting goes up. And the resistor at use fine the intensity of output signal. The detail is other , see in circuit picture.
