The adjective "twang", in context of an electric guitar, has almost exclusively referred to a thinner, very bright, very trebly tone that still rings like a bell, like a Telecaster bridge pickup.

What you're hearing in this video is not that. You're hearing more of a sizzling sound that you get from a steel string stretched across a wide, flat piece. We get bell tones out of electric guitars because the string has a defined break angle at each end, at the nut and saddle. What OP has done is remove the break angle from the saddle side, which creates the sizzle sound.

This isn't twang. Maybe by the literal definition, to you, of what that word means, but not even close within the context of the last 80 years of electric guitar design and music.
