Aion Blueshift - DC-2 Dimension C - Depth

[destro]

So I have built two of these suckers (I like building doubles to compare and troubleshoot) and one sounds deeper than the other. I think the one that sounds deeper, could be a smidge louder which might enhance that effect. Lacesensor pointed out r9 being a resistor that can be adjusted for volume, but I was wondering what may effect the overall depth. The one I like sounds dimensional, the other one chorusy and could use a bit more warble. I've attached link for build doc.

So after looking at a few different schematics, I found one that labeled the switches between ic5b and ic7b as depth and switches between ic7b and ic7a as speed.

When calculating out the parallel resistor combinations for depth, not switched is 22k, switch 2 is the same, switch 3 would be 21.01k and switch 4 20k and switches 2,3 and 4 would be 19.18k. Not a big difference between 22k and 19.18k so I am Gonna compare resistance at r38 between the 2 and see if there is a difference. For speed there appears to be two options, unswitched 330k, switch 2 no change, switch 3 65.6k switch 4 no change.
