try this,
you are playing E pentatonic (E-G-A-B-D-E)
change a note, lets say make the G->F# and play this scale
E-F#-A-B-D-E all over the fretboard untill you get used of that sound, then change another note and so on...

you can record yourself playing a few chords and then jam over that, since you know the E pentatonic you can record chords like Em Am Bm C, this will also make you a better rhythm guitarist

And always listen to what you play
