Saturation Knob is a free plug-in, but you do need to get a license in order to run it.

First, set up a Softube account, and make sure to link an iLok account to it. Then go to the Saturation Knob product page and click the green “Buy: FREE” button. 

A license will be sent to your iLok account, and you can then use the Softube Central app (found under the “My Account” tab on our website) to install your new plug-in.
