I would try learning as many different scales as you can and you will naturally stop phrasing everything with a bluesy feel. I learned a lot of different
minor scales and it really helped me get away from my blues sound that I kinda got stuck on. One of the best books I have is Chords, Scales and Arpeggios by Al Napolitano, I've had it for years so I don't know if it's still in print.
