So I just fashioned myself a slide from a bottleneck, not quite sure how to use it...
Brilliant. i kudos you sir.
Make sure your action is high and don't push down on the slide, just let it rest on the strings. Also you're gunna want to have your fingers resting on the strings behind it. For example if you have the slide on your third finger, place your first and second fingers on the strings behind the slide. Hope that helped a bit.
Haha, love it!
