I soldered all the components together and my signal gets through both when bypassed and activated but it appears that the spectrum function doesn't work? The tone, regen, and dispersion pots all seem to work fine but the spectrum pot seems off as the frequency/pitch doesn't seem to change as I rotate the pot. When I measure the pot at the extremes, it measures at 1.5K ohms. At first I thought it was the pot that was a dud, but outside the PCB it reads at 50K ohms. It's my first pedal build and I am stumped.
