If you like the pentatonic minor & blues box, you'd probably like Aeolian (Natural Minor) & Phrygian modes of the major scale.

E minor (Aeolian) : E F# G A B C D [E]
A minor (Aeolian) : A B C D E F G [A]
E phrygian : E F G A B C D [E]

Go up and down the fretboards with the same patterns to change the root of the scale (mode).

You should learn the major scales and how to make modes and chord progressions out of them.
