In the bass community we often hear the phrase "less is more". This annoys some people to no end, they reason that less is less and more is more.
Of course they're missing the point, which is why I propose the "less is better" substitute.
In most cases when it comes to bass playing, less is better. I say most cases because there are times when you do need a little bit more in the bass line, but for most situations the less is better policy works very well.
