Hey, thanks all. I ordered a few at different times, Builder and module 8 to be used in the arachnid. As dumb as it may sound, I'm only using these for one or 2 of the programmed effects. No rotary switch, just a jumper for the effect I am using for the build. Some are Flanger, chorus, and for an octave up on bass builds, I like the pitch shifter of this pcb. I just have no clue which chip is for what. So I am wiring them all up for normal use to see what I have, will modify accordingly and keep better notes in the future. Thanks!
