I think noise coupling into ground could actually be a big issue. Depends if that ground is earth or just a local reference. The other wires still have “antenna” features though, so that’s the obvious worry.
No need to worry there, a 1/4 wave dipole that’s under a half inch will only pick up the microwave band. It’s plugged into some kind of instrument amp and those usually have decent filtering on the inputs to keep out weird crap not in the audio spectrum.
Especially with that makeshift antenna hanging 💀
The antenna looking piece of wire is the ground so it doesn’t matter if it picks up anything.

That’s the ground. It’s probably not an issue.
