For that I recommend “mindless noodling” Set a metronome (important!!) Then set your fingers on the fretboard and just start playing notes in time with the metronome.
You can start just doing E: 1-2-3-4 A: ————-1-2-3-4 D: —————————1-2-3-4 G: —————————————-1-2-3-4
And then back down the same way. What you’re looking for is each note is on time and the same intensity.
It’s easy to do and genuinely helps.
After a set, move to a different position but play the same shapes. You can also move from 1-2-3-4 to something else, like 4-1-2-3 or whatever.








Would you care to elaborate?
