I highly recommend getting a teacher. If one blames inhibited creativity on the teacher, then he just isn't willing to admit that a lack of creativity comes from one's own self, not from someone else. Unless your teacher forces you to play only his licks and NEVER make up your own, then I'm going to assume that he will not "inhibit creativity." He will, however, give you ideas that you can build upon, nto only that, but it is really helpful to have person to person lessons when learning new techniques.
