Spend time w/ your major scales up and down the neck. The seven distinct patterns which if you memorize them, (uggh...hate that word.) will really be a great jumping off point to do almost anything. Modes : The Aeolian mode (natural minor scale) is probably the most useful scale in rock there as it meshes perfectly w/ blues patterns. The Mixolydian's funky and the Phrygian's spooky. It’s all there.
So bust out the metronome and choose one day a week to learn them. DONT front on the major scales!
