I notice the people who play slide guitar actually have shortened the slide. I will be playing the slide on my pinky and I noticed that Griff as well as any others including Clapton who use their pinky have shorten the length of the slide ( tip of pinky sticks out some at the end) they use. How do you decide how long to make the slide for your pinky? A general rule is all I’m looking for. Thanks and to care, Jay
