This kind of has the sound of someone playing an acoustic guitar patch on a keyboard. It seems to lack the expressive dynamics you would expect with a guitar, almost like the velocity is clamped.

It is noise gated, which could be what you’re hearing. (This lets you play more piano like and not have to mute all those open strings)

[MrScruff]

That's probably part of it - also seems like if they're mostly doing a pressing rather than a plucking action it would result in this sound?

[HelloNurse]

Why do the strings need to be muted? Is there so much resonance that playing quickly would produce indistinct humming?

[uxp100]

Probably a factor, but I think it’s more for ease of use with all those strings, so that incidental contact isn’t producing sounds, along with the pull off energy when releasing notes. You do a lot of subconscious muting when playing a guitar for example.

It looks like it is mostly played with hammer-ons? Maybe is someone plays it one-handed and adds a pick you get back to the guitar dynamic range. But then what's the point (may as well go with a lap steel guitar then).
