Shielding the cables was indeed the hot ticket. Suuuuper excited my $25k+ education barely mentioned this at all.

Note to self, making my own cables is a PITA (pic related). Is there any foil or braid wire out there with just one conductor? I never used the other conductor in my diy cables and I'd like to cut down on bulk/clutter with the final build.

Running my circuit bent stuff through it, seems the low power instruments (2xAA) get drained in the 'off' positions as the LEDs on them go dark even when pressing buttons. Not a big deal.

However, some have contact points will still bleed through in 'off' mode. I've found tying these points to the input ground on my mixer rectified this, but is there a more practical way to go about retro-balancing unbalanced electronics (assuming this is a balancing issue)? I thought buffers might be the answer but I don't see how that would ground the contact points.

Also, is it better to connect all the shield lines to chassis? In pic related, the 'chassis' was cardboard so all shield lines were strung together ( and eventually to ground on in+out).
