Lol it works like a charm, I accidentally used a black wire for the cutoff that should have gone to -12v so i hooked it up to ground. turns out, you kinda need that ref voltage to get your full range. I swear the previous time i built it i hooked this part correctly but made some other error. now, after combing all of the connections on the board, i noticed that the -12v i was expecting was basically ground i was like whaaat. So yeah, glad that’s sorted.
