In the words of Vemuram:

The Butter Machine was developed in collaboration with Michael Landau to create his ideal distortion pedal. We have made countless prototypes, which took more than 2 years in R&D. Having Michael use the prototypes at his sessions and on tour, we were able to hear his direct feedback and aim straight for his ideal driven tone. In addition, new ideas were implemented, and various improvements were made by testing the prototypes at his recording sessions and at his home studio in Los Angeles as well. As a result, we were able to create a new type” of distortion pedal that is user-friendly and wide in range. It allows you to control your picking nuance and dynamics, and the drive goes from overdrive to full-on distortion effortlessly.
