adding a presence control to mhartman sss layout

[solow1977]

Could i change the values from 270 to 390 and 2.7k to 4.7k, then add the 2k pot with a 1uf cap lik in the ODS amp? Does this mess with the cf part of the phase inverter? Or is there something else I should consider? Thanks ahead of time for any help

That should work fine. It won't mess with the CF. It's been a long time, but I think I might've get have added a presence or contour control to the back side of mine.
