I was playing a show, and for the life of me, my fingers (picking primarily) would not work for me. Slow, sluggish, doubling up, speed was off, timing etc etc. Keeping an eye on the setlist, I saw we had a busy bass song coming up, and we had to pass on it. This happens to me every once in awhile. Sometimes the fingers will let me play Jaco, sometimes I can't even play -insert easiest bass players lines here- ie U2's 'With or Without You'. Before most gigs, I will warm the fingers up with some stretching and scales to get a feel for how my hands are doing. Usually they are good, but the odd time... Does this happen to others? What do you do in these situations? Play through? Ease up on the playing, aiming for more root note basics or what? Advice?
