I'm very new to slide guitar playing, so this might sound like a stupid question. But I'm trying to learn this "Georgia on my mind" cover on a slide guitar, and I ran into a doubt.
Sometimes, like on 0:24s and on 0:28s he seems to press on a fret that stands before the slide, which I didn't think would do anything (I thought I was missing something, otherwise why would he press the frets?). But while I was playing around trying to figure this part out, I realized that pressing a fret before the slide actually works because the bottleneck is only slightly touching the strings, so when you press the fret it goes a bit down and stops touching the slide.
Is that what he really does there? Or is there something I'm missing?
