Wow, great work! I have the same board and almost the same ideas after looking at the filter section of a Radial Tonebone pedal. But I never started it as I was looking to complete my Super Sonic build. This article, rather a short book, has inspired me to break out the board and dig deep into my component stock.
It’s members like you that keep this place rocking. Thanks so much for all your work. I was wondering though how you apply your graphics sheets so thanks for the idea. Everyone has their way and I have yet to find the perfect way. In fact, it has been the toughest challenge in all my builds. How about the diodes? Did you ever try Mosfets?
Anyway, thanks again. Keep up the good work and let’s wear those soldering irons right out! -Dave
