I did, in fact, goof 🙁 I was testing the wrong pin. But, I got it right tonight 🙂 Thanks for the redirection.
There is continuity between the middle pin of the depth pot and pin 23. And pin 23 measures zero to 4.988 as the depth knob is turned from min to max.
Is there a likely culprit (like stray solder) for connecting the depth pot to the rate LED? Everything works well once the rate LED starts blinking, including the tap switch. But thorough most of of its range, the depth control makes the rate LED stay on.
I appreciate your help diagnosing the problem. I’ve built around 10 pedals so far, and only one has been a complete disaster. But, clearly, I’m still learning the ropes. Oh, and I’m building your Altura right now. So far so good!
