Reading the pinky post made me think about a problem I am having.I am trying to play this nice little progression up the neck from the Peter Green era Fleetwood Mac song called Need Your Love So Bad. It is 5/7, 8/10, 10/12, 11/13,12/14 on the first and second strings. From 10/12 on, my ring finger is muting the first string. I can't seem to get a good enough arch. I tried putting my thumb in different positions and have had it ring clear but my hand is really uncomfortable. Any tips or advice?
