I honestly think guitars aren't higher technology, all they do is allow you to play multiple strings at once, with the downside that they're now fixed at one tone each. This in itself corresponds to how the grey remote moves on the color grey, while our is tuned to black which is a different but very similar base frequency, there's just a slight difference, maybe it's only in the length of the frequency band, which is why installing the grey remote for us leaves it "open" on the far end. That actually makes it look the same as your drawing here:

What the blacknet installer does is to attach the lose end of the string so that we reach black magic. Greys seem to perhaps leave the far end open so that they can choose themselves at what length to attach it. I think that's the only difference.
Greens have their remote at the lowest frequency but change the color band instead. If you're interested in trying green tech you need only ask for them and they will come. But if you do, make sure to not leave the color tuning open, it makes the device very unstable. It needs to be locked at a color or the thing moves all over the place. This is more like a guitar or a base, which can move between colors (strings) while those are in fixed tuning. Still it's just using more things at once, all of this could be done with just one string.
I found an entity using a single string instrument like the one I posted above and it does work like I suggested, this is giving me a new understanding of music.
