Distortion v1.2

I forgot to add the output gain op amp to my distortion circuit, so the output was 1/11th of what it was supposed to be. Here is a corrected version:

 

In the previous version, I buffered the output from the resistor voltage divider. This is not necessary as it is fed straight to the positive input of the distortion op amp, so I could use that op amp for output gain instead.

At 5V CV the output is unity gain, whereas it distorts at 0V.

A +/-5V signal passes undistorted through when cv is 5V. A +/-10V signal distorts slightly. The output never reaches higher than +/-9V so no clipping.

With CV = 5V and input 10Vpp, output is 10Vpp undistorted

 

With CV = 0V and input 10Vpp, output is a nice distorted signal at around 14Vpp

With CV = 5V and input 20Vpp, we get a bit of distortion, output is around 16Vpp

Finally, With CV=0V and input 20Vpp, we get heavy distortion, but the output is still not more than 18Vpp
