Has to be Meshell Ndegeocello. She's 5 foot and apparently can't reach the headstock tuners, but what a great player and songwriter.
As for Gail Ann Dorsey; nice player, but maybe a little limited in some ways; anyone noticed she is put on rhythm guitar duty when Bowie performs 'Ashes To Ashes' - the one song you would really want to play, as a bassist in the band.
It has got to be the queen of bass... Ms. Carol Kaye!!! - She gives the term badass new meaning. Without her bass would still be back in the stone ages (for both male and female players) - LOOKS BE DAMNED - SHE CAN REALLY PLAY!
