Output Problems

[Kipper4]

So my breadboard circuit currently has an output that looks like this.
I've been up half the night getting it to this and Its way better than my previous scheme.
(lots of loading issues and interactions in last try.)

But its far too interactive.
Turning the pots kinda screws with everything else, Like an annoying hard to set tone stack.
As soon as you've set the low end, you start concentrating on the upper end and it screws with the low end.

I can't think straight. It's been a tough week.
I think the answer is a seperate buffer for the "Dry" signal. Maybe each signal (wet and dry) having a variable resistor to the inverting input to independantly control the gain of each signal at the output.

Looking for someone whos more switched on than me right now to guide me through this output challenge.
What would you do?

maybe ?

Deep breath...
If you have the input from an op-amp, you have a strong driver that can feed several paths without them interacting at source or needing any additional buffering.
Where you have an op-amp inverting mixer, the input paths don't interact due to the virtual ground at the -input. However, that situation can only exist if the op-amp output isn't clipping so don't boost anywhere too much.
You probably don't need a dry path to have much more than unity gain. Design the wet path to have any gain adjustment instead.
Where you have an RC network, the following circuit might need to be about x10 of the RC impedance. Rule of thumb is x10 of the R in the RC. If you don't want the RC to be affected by an unavoidably varying load, then buffer it. With a low impedance source, the RC values can be re-scaled for a low R so that the following circuit can be lower values too.
