hi all. i'm kinda stuck on 1 or 2 scales each time i'm solo-ing over a backing track. on top of that i rarely go past the 1st octave. i know the 7 scales well enough i think. but somehow even when i'm using the key of C, which i pretty much know the place of each scale inside out, i still find myself stuck using a few scales only. this is more pronounced when i increase the tempo. any ideas how to improve on this?? thanks
