I have uploaded the Tube/Distortion 2nd Edition Book Addendum and it serves to augment the information in Chapter 19: Nonlinear Processing. You can snag it for free here:

This is a massive addendum; not including the added patents, it was about 150 pages of additional material not covered in the book. It is a long story, but the publisher made me cut some stuff to shorten the book and this was the only chapter I really eviscerated. The new Addendum has two bonus projects: a distortion box model and a complete combo tube-amp model complete with reverb. The tube amp simulation is something people have been requesting for a long time, and as you can see from the addendum, it is almost its own topic/book and I probably should have spun off another whole book on the topic. Anyway, I hope you like it and that it helps make Chapter 19 more complete, and totally KICK-ASS!
