I don’t play slide guitar often and I’d like to practice it and get better but when I try it, I can never get it to sound good. I know practice will clean up a lot of it but in terms of sound I want to make sure Im Doing the right things. I use a line 6 variax guitar so I have access to multiple models of guitars as well as tunings so Open G or sliding In E isn’t an issue. My guitar has low action. I use a glass slide. I tend to play hotter Marshall’s in my FM9. What amp sounds are generally best for slide guitar similar to Derek Trucks or Ian Thornley. Thornley sounds like he uses a lot of gain for the most part
