i agree with the combination.. with boss aya too..
but if you're not fluent with music theory, very much like me, i'll go with "feel". I know my pentatonics, blues boxes etc, but that's it. so from there i improvise guided by phrasing and what i "feel" what's right, i'm kinda emotional and i think it also helps me do expressive solos and rhythms. hell, sometimes i don't even know what scale/mode i'm in. but what the heck, works for me. even my fellow guitarist friend says i have more "lagkit" and i can only trust his ears.
but with that being said, still kapos pa rin. that's why as much as possible i study theory to learn what i need to learn.
