Well, I guess I can give some general tips, based on what you're saying. However, it looks like you are already doing much of what I would suggest. To make the Funky EP more prominent, raise its volume -- but I see you've already made it louder than the dual voice. But, you can try making it even louder and/or reducing the volume of the dual voice. You could also try experimenting with the filter -- by slightly raising the cutoff and resonance levels (if you raise them too much, you might get too much of a twangy sound, but a minor adjustment may just bring out the sound the way you want).
I see you have the chorus and reverb both higher on the dual voice than the main voice -- I would try switching that. Or at least increase the chorus and reverb on the main voice (without adjusting the dual voice). I'd raise the chorus more than the reverb. And, you might want to try different chorus types. Which type of chorus are you using? Sometimes the flanger can fatten up a sound, if you don't set it at too high of an amount.
