Here’s how to setup a guitar for playing slide guitar. You need to have the neck lined up right, and have the strings a little higher than you normally would. If they’re too high, its hard to play the frets, and if they’re too low, you can’t get the smooth slide sound. This guitar is setup with 11 gauge strings.
