I was hoping someone could have a look at my wiring to make sure it looks reasonable from a grounding point of view. I recently built a few pedals and they all exhibit a slight hum when bypassed. The hum goes away if I touch the foot switch (the external toggle) with my hand. I tested that I have continuity between the following (I'm assuming that this is expected from what I've read here): enclosure (probed on the inside around the foot switch where there's less powder coat), I/O jacks (the washer on the outside as well as the ground points on the inside of the case), foot switch toggle on the outside, shield around the wire where applicable. I attached a couple of the builds, one with a shielded wire on the input and one without.
