Contact! Steve Fishell
Steve Fishell has agreed to view the video and is open to my visiting him when I'm in Nashville in early May!
I explained in my email to him that I've already made improvements since the video was shot:
After installing the latest version of the pickups and a newer circuit board, and after making some changes in the input power, the sound is much cleaner than heard on the video.
I replaced the very ugly breakout board with a much cleaner one.
I replaced the hack-ish, local-hardware-store brackets, used as pedal stops, with something I designed and had 3-D printed.
I replaced the micro-controller with a much smaller one which has more inputs for pedals and levers.
