Guitar Soloing, and improvisation in general, is a complex subject. But no matter how many techniques and exercises you practice, they are useless if you can't use them in a musical way.
If you've been following EMP for a while, and watched some of my solo guitar lessons, you probably already know that one of the reasons I prefer using the String Fragment System, instead of learning box shapes for scales, is exactly because it helps you play more musically.
