Big muff depth control- rullywow

[turkeypills]

I'm trying to build a muff with features from all of my favorite muff clones. I'm using a rullywow king tut board but also have an Aion electronics halo. Not sure which would be easier to apply the off board mods to.

I'd like to include the depth control from the Earthbound Audio Supercollider but how to wire it in has me a bit confused. I can visualize the pot in parallel with a smaller film cap with a 10uF tantalum attached to lug 3. What I'm not sure of is where to attach the wire from lug 2 of the pot. It looks to be in series with the rest of the depth circuit but the base of Q4 and R14.

Any idea how to go about doing this?

For reference I am using the rullywow schematic and the Kitrae schematics for the pharaoh and supercollider.

The pedal will be done to civil war spec with 1st and second stage clipping toggles with a JMK clean blend.
