I was curious how I would most efficiently go about have both the volume mod and CV expander. I currently have the volume mod built, and I stripped a jumper cable with enough length to feed into the VCA in. I then closed her up (making sure the jumper wired to VCA In was still in place) and connected the CV Expander. Ive noticed that with this setup, I get some noise when the jumper cables are moved any small amount. Im very new to this stuff. Is this setup done correctly? Or is there a more efficient way to make use of the Volume Mod and CV expander?

Cheers.
