Simple, start playing whole chords and start practicing scales.
and songs that require full chords to be played
Additionally what you cna do is replace the riffy songs with chords.
That means supposed you are playing a song which has riffs in it, try replacing those riffs with chords, and try to make it sound good by strumming.
The fact is you gotta do these thigns on your own.
And hey, practice on clean tone, slight overdrive is acceptable, but no distortion.
You donít get what you deserve, you get what you negotiate.
