Personally I think that theory can be very important and also a GREAT advantage and opportunity for you.
Knowing theory helps you to learn and improve:
- Improvisation
- Songwriting
- Aural Skills (when Transribing Music without having tabs for example)
- knowing chords, scales etc. faster and expand them quickly
Think about learning a new language but only learning all the words and all the vocabularys WITHOUT thinking about grammar. Would be bad, right?
Theory shows you how it all works and how it all fits together it is the bottom of all the other parts of music.
Of course this does NOT mean that you cant be a good guitar player withoug knowing theory, but actually you can be an even better guitar player (and become on faster) with it.
Hope this helped.
