Cool harmonic tremolo

I built this with quite a few mods. Changed the output cap to a much smaller value (68nF instead of 1uF) and put a small capacitor over the volume pot to tame some highs (4.7nF). Also added a Buff N Blend to blend in some clean signal. The original sound cool but these changes make the pedal more transparent and less mid scooped. I also tweaked the LEDs quite a bit since their distance from the LDRs really affects the sound so use your ears to find what sounds best for you. I soldered the LDRs flush to the board and bent the LED legs to almost a U-shape so that I could easily change the distance.

A cool circuit and build! A little bit of tweaking with the distance of the LEDs from the LDRs but nothing too tricky.
