On Ken’s build page for the CGS01 he states;

Don't make the same mistake I did and tie all the wires going to the pots together. This causes some crosstalk. Either keep the wires apart, or use shielded cable.

I have built several of these excellent modules and left the wiring unbundled and they work great. I was wondering, however, if using wiring with an insulation diameter of 0.41mm (0.016”) would solve the problem and let me bundle the cables for a tidier look? I’d actually like to twist the wires but that might be asking too much.

AFAIK the plastic insulation itself has no shielding properties, it may change the capacitance between them but wouldn't shield them as such. If you want to bundle them together you could always do that with what wiring you have and see if it makes a difference? If twisting I'd twist each cable with a GND wire, that may help act as a shield of sorts.

Thanks for the tips. I'll do a little experimenting and see what I come up with .
