It may seem obvious, but try playing outside the "box"..I used to get locked
into "pentatonic" scales and the modal scales...but try visualising angular patterns and shapes on the fretboard. Try any shape that comes to mind of course you'll hit clunkers on the way but it will get your fingers used to odd patterns and eventually be able to hear some kewl stuff. Arpeggios are a good way to start, but even some of those have become "standardized"
just pick shapes within a 7 fret distance from one another and try to pick out chords, skip strings etc...that will also help develop your reach
hope that helps :cool:
