The amplitude is not consistent at speed. Why should it be? I am fast. Any fair distortion pedal can also redefine the envelope quite nicely. It will take about a month for me to put together the next 60 pieces if the xmas sessions are too difficult due to complexity. the new batch will be solos, not duos. Perhaps easier on the less jaded and mature ear. I even have a few with the zombie theremin pedal. the kmise crunch distortion does some sweet tone modification.
BTW - my broken arm has started to heal, so function would improve.
