Muting strings with your left hand also is important I’ve found out through my experience with playing slide. Just have basically the same amount of pressure as you do with the slide (just enough). Also the tone and volume knobs on your guitar are very critical, i usual have my tone down to half if it’s more ambient and around 75% or more on songs that have more aggressive slide parts.
That was super helpful! When building a patch, how do you know how loud the patch and each snapshots should be to sit correctly in the mix without the need for someone to ride your level throughout the song?
