Clipping Diode Experiment

Posted on July 24th, 2011

After working on a 3-channel mixer for a friend i started thinking about diode clipping the output of that mixer to get some extreme distortion effect. (it has quite a lot of gain) I had seen some pitcure of how clipping worked but i didnt realize how easy it was! Just connect the diodes between the signal and ground, if the signal is to loud it goes to ground and gets silenced by the diode. It clips. I had to try it! So after hooking up two tele-jacks with the diodes (as seen in the pitcures) i fed it some different waveforms from my nordlead, starting of with a triangle to see if i could get it to clip, and it did! But it didnt have enough gain to get it to clip properly so i fed it through a mixer to crush it in to the poor diodes with a little more power. The results can be heard and seen in this post. There is even a little scematic i found somewhere. The clipping i used was hard symmetrical clipping. (I really like how it reacts to a sawtooth with full resonance on the filter.)
Peace!
