Wondering if I could swap the 1.5uf cap at c16 for a 1uf? Taking a look at the schematic I’m not sure what kind or how much of an effect it would have coming out of that ic and into the bass control. Any guidance is appreciated
If you make changes to other components to hit the same frequency target, you’ll alter the Q of the filter. Try a 1uF and 470nF cap in parallel to get you there if you don’t have a 1u5 cap.
