We started this project a year ago, a brief history of our project can be tracked on the Muff forum and instagram. We wanted to create the exact replica of the 909 and now we've built the first accurate copy of this classic drum machine.To begin with, we decided to study the circuit and its components. Then we had to look for alternatives to mechanical parts, they don’t affect the sound but they are pretty rare and expensive, and sometimes they’re not available at all.
To keep the sound of the original 909 was our main task and I think we’ve finally found good solutions. And now we are ready to share our project.
