OLD SMOOTHIE

The Old Smoothie is a basic op-amp distortion with a bit of a unique feature: you can adjust the amount that the diodes clip the signal. This means that, by turning the “clip” knob, you can control how squared or rounded the sound waves are and get slightly different harmonics and timbres of distortion. Turning the knob to the right increases the amount of diode clipping, resulting in more distortion.
