EDIT: Had a bit of a clipping problem initially, but seems that I just had the volume trimmer too high. Cool project! Will try to post a demo later.
Here's a boring demo, clean signal initially then dialing through the settings a bit. Ibanez JS1000 --> Rub a Dub Deluxe --> Marshall DSL401 --> Studio Projects B1
