Here it is, very simple.
If you're in E,... E, A, B or all 7th'd, play all your blues licks. Which is, an E min pentatonic or a G maj pentatonic. It all depends on your point of view or maybe how or what you have learned first. (ironically modal)Playing either point of view will work, and SAFELY. Most all American music oriented guitar players START this way. The interest, mostly, is what is heard. Normally and upon reflection, E A B, depending on what you have heard thru life, you will play, pentatonically, an Eminor or G pentatonic, or Emaj/C#m pentatonic, depending on orientation. Beginning and intermediate guitar players,
mostly, play this way. They'll will do extensions, because their favourite guitar players do the same. The key is understanding the sound. Playing and/or learning positionally will make clear all pentatonic knowledge and logic.

If you are not a pentatonic player already, this will be hard to consume. Major and minor scales are simply modified pentatonics. Control is based on pents and musically determined by pents, especially in terms of more advanced music. They are, overall, very basic arpeggios. Knowing pents, saves a lot of work. They're the key to all American music's logic.
I hope this helps,
