I had a similar situation with my guitar playing, wanting to reignite my playing as covid lockdowns were trying to happen here and there. My daughter suggested learning slide from a player on fb. He taught through fb messenger, starting probably around June or July last year. Fast forward to the present and I'm playing all things slide in standard and open tuning! Because I was able to have someone show me the mechanics one on one, I got it down. Since then I've exhausted everything slide that GT has and believe me, they've got some great stuff such as Curtis Lowe, Statesboro Blues, and the awesome Zeppelin song, You Shook Me. I play in a church Praise Band and I turn at least one of our songs each week into a slide anthem. Never stop growing!!
