The last part of the first video makes it more clear: you're basically your own bass backing player with one or two notes. I see why he trademarked "palmbass" as another term.

which is exactly the role of the thumb in classical guitar

so this is solving the fact that using a guitar pick forces you not to use your thumb

I’ve not played classical guitar but on a standard electric guitar I just don’t have the finger length to fret the low e and the higher notes at the same time, and I don’t have freakishly short hands either. So it can help with that, pick or not.

I thought on an electric guitar the strings are closer together though? And the neck is thinner?

		Maybe! I’ve never played a classical guitar.

that doesn't sound normal. You can get more grip by curving your hand around the neck so your thumb rests a bit lower like on the middle of the neck. If you have an average hand size, i think it can be fixed with pratice and technique, finger length is not the issue

		I misspoke, I meant I can’t fret the low e with my thumb while also fretting the higher strings. I can mute it, I just can’t fret it Jimi Hendrix style.
