we do this tune, so i've had a pretty deep listen. i don't hear any delay in the verses at all. i just play it with alternate strokes on the G#, occasionally hitting an A#, which i'm also holding down.
also interested to know where you think there are harmonised parts...?
that's a pretty nice version
to be honest, the verse part is so inconsequential, it's hardly worth bothering to hit a switch to add in some delay...nobody will notice it...
