I've built this pedal and I have two things to say about it:
1. Sounds FANTASTIC. It might very well be my main go-to tremolo now. I'm extraordinarily pleased with how straightforward the build is.. the layout is clean and well thought out, the sound, and the controls. It's a great project.
2. EVERY SINGLE ONE of my "harmonic tremolo" builds has been a crap experience. I don't know what the hell the problem is, I tried the Cardinal on both PCB and vero and neither works. I tried the Baja one, nope. I tried the Pareadoliwhatever... nope! The Twin Peaks... BAM! fired right up, just lovely and sweet.
