[sdiy] simple nasty clipping?

[Oren Leavitt]

Hi Greg,

A passive approach:
Try Schottky diodes. They might give you a harder clip. The amplitude of the clipped signal will be small at less than 0.4V pp.

Active approaches: (will need to be powered by your device)
Try a Schmitt trigger - It'll give you good hard square wave output.
Give it just enough threshold so that the noise floor doesn't fire it.
It can be constructed with a couple of transistors, or an IC, and a few external resistors.

Or an op-amp with the doides in the feedback loop will give the signal level a boost and clip it harder.

Take a look in the SynthDIY archives or check out some of the DIY guitar effects sites for more ideas.

My few bits,
Oren

hi,

does anyone know of a really nasty really simple distortion circuit? i tried 
the two diodes shunted to ground, and it was nice, but not tearing. do i 
need to somehow boost the level first? i'm trying to build this into a 
pre-existing device, so small and simple = better.
thanks,
greg
