Does anyone know what chords and scales are used by Buckethead in this song?
I skimmed through the tab and it looks like G# minor to me as well. Beautiful song.

Abm and Emaj are the chords. But I think he's tuned down a half step, so it would be the Am and Fmaj chord shapes. As for soloing, I think he just sticks to the A minor scale.
