Two 4.7 k resistors between IC6 and IC7 and IC9

You have speak about this in another post but I can’t find it with the search.
I have already solderet them. I’m in 60 % to end. What do the two resistors do? Is it better I cut them off before ending?

Which filter board is that?

Sorry, dual svf.

Putting the resistors here will give less distortion and a bit more background noise. It’s in the “barely noticeable” range though ; and I don’t bother with those in new designs.

I’ll cut them I think.
Thanks for help, maro
