Designing an exciter

Hello again,
I have cleaned up the design a bit, optimizing the OpAmp count, when I noticed that the original design had the ‘Dry’ band inverted before summing it with the saturated band.
So my question is: Should I add an inverting OpAmp at the red ‘x’, or should I switch the signal from Inverting to Non-Inverting at the blue ‘x’ ?
