Ha ha ha ha. That is one awesome build! Which LDRs did you use? What process did you use to set the trimmers? What's with the mix of opamps? I'm guessing you ran out of TL072s.
Just FYI to anyone who is interested in why yellow LEDs are recommended, Cadmium Sulfide LDRs are most sensitive (by a long shot) to light between 500 and 600nm. Yellow LEDs peak out at 570nm and green around 525nm.
I have the board and am collecting the parts. I've got some mods in mind, of course. One side is gonna be tuned like a Uni-Vibe, only with six stages instead of four and a switch to take out the two extra stages. Also thinking about a Blend knob, a Throb knob à la The Abyss, a triangle-to-sine converter for one of the LFOs, throbbing LEDs, putting one or two of the trimpots on the front panel... Definitely some experimentation is gonna happen!
