Ok, let me say this, about that. I set it for LFO blinking, and it's not blinking. I do have output and a steady light when switched on, and it actually sounds like it's stuck in one part of the chorus "movement". One more thing, that 22k resistor is soldered into the board.

The LFO isn't working. Check your work at the 68k, 82k, 120k, 470k, 47k, 180k resistors, the 2.2uf and .047uf caps, and the 1M pot.

No. Clockwise would just be slower and CCW would be faster.

I think I may see a problem. It looks like some of your solder joints are touching the standoff holes. Those holes are sometimes actually vias for signal and/or current and the chorus is no acception. I tend not to design the boards like that anymore because some people who source their own parts appearently like to use metal standoffs. ANyways....hope that helps.

well, I re-flowed all the suggested caps and resistors...checked the standoff holes, (the solders are close, but not touching, and re-wired the 1mg pot...still the same as before...so close....

Went back again (record 119 degrees where I am, in the black widow garage), and still can't get it.
