Question about sending ONLY the wet signal

How do I get only the wet signal through an aux input?

So the bus chain setup I have is this:

1. Vocal source track - routed to aux a, b, c.

2. Aux a - Main compression (2 compressors, eq, desser, reverb, delay)
3. Aux b - Thickening (Doubler, eq, imager)
4. Aux c - Parallel compression for bass (eq, compressor)

Now what I want to do is increase say the "aux c" send so I only get the effected signal NOT the effect AND the original audio (Vocal Track).

At the moment Im getting both which makes mixing vocal impossible as it cant cut through given every send carries with it the original, flat signal. :confused:
