I want to create an guitar distortion effect. What I want is a unity gain buffer op-amp that clips the signal. In the drawing below there is a circuit found on this forum here which will clip a very low voltage (~200mV) signal. However it will only clip at a particular voltage. What if you need (as I do) to clip simply the peaks off every wave?
I could provide some sort of rectified average peak of the input signal int 'mclamp' and 'clamp' such that the clamping voltage roughly followed the input signal as it rises and falls. For this I would presumably use some sort of 'ideal' rectifier (because of the 0.7 breakdown voltage of a diode bridge).
First.. is there an IC that will do this that anyone knows of? And secondly.. Is what I'm proposing viable?
