Welcome here 
if you have wired thinking that the pot was seen from behind on the schem, and you want the reverse, just imagine that the pot is seen from the front.

Yeah, to reverse the direction you usually need to swap the outer connections, leaving the center untouched. I am not sure if that alway works, but I guess so

It has to do with where the wiper sits on a resistive material. By swapping 1 and 3 you swap where the ground and reference voltage is, which changes the polarity. if 1 were gnd and 3 were 12 v, if the wiper were positioned where it is, it could be like 5v on the output pin 2 or something. If 2 were 12v and 3 were gnd, the wiper might read like 8v.

Thatâs if itâs linear taper, of course. With audio taper it would still be reversed direction when you swap 1 and 3, but itâd also go from log to reverse log behavior.

Oh right, didnât think about that case. Mostly cause I didnât know.

âWow, youâre such an expert on what happens when pots are wired backwards! How did you learn all this?â
âWellâŚâ

Thanks all for the quick (and helpful) responses! After taking a couple days away, came back and saw errors in my placement of the 100k pot vs the 47nf cap (yes, even super-simple isnât idiot-proof!) ⌠then tried the âreverse what you see in the diagramâ approach for the pot that you recommended.
All good now and making happy little buzzing sounds (the oscillator, not me.)
Thanks again!
