When playing the bass guitar, having good callouses on the fingers of both hands is only slightly less important than having an instrument to play, and is certainly more important than an amp or an appropriate string guage or stomp boxes or a badass attitude or musical knowledge.

Don't believe me? You try grooving on round wound steel strings for 30 minutes with virgin fingers, and just you wait and see how much skin is left on your fingers and how much is embedded in the strings.

This could be one reason why chicks dig the piano player, or at least prefer him over the bass player: a pianist's hands aren't usually a glove made of dead skin.
