I've been memorising the mixo scale for a while now but I am getting some concerns with my fingering. For example, the first scale in A starting on F#, to get to A on the bottom E string I strech my pinky and that works fine. But the first B scale is giving me trouble. On the bottom E string I use my index finger for F#, middle finger for G# and ring finger instinctively goes for A. Its a bit of a strech and not that comfortable. But using the pinky for A seems to be just as bad, is there a certain way or a technique that you guys know about?
