    it evens out the high and low volume in your signal. if someone were talking, it would boost their whispers and turn down their shouts to (for example) normal talking levels. The range between quiet and loud is called dynamic range. A compressor basically squashes the dynamic range. It's a useful device for bass playing because going from fingerstyle to slap is a huge dynamic range. So if you're playing at a good volume fingerstyle, the slap can really pop the speaker if that signal is not attenuated a little. And even if you're just playing fingerstyle, it evens out the volume.

    Some bass players swear by them. Some hate em.

    There are sound samples on: http://www.analogman.com/rossmod.htm#comp

    You'll probably listen to those sound samples and say "***? i don't hear any effect at all!" That's because popular music recordings are really compressed using studio compressors. but it's definitely something you would notice playing live.

    Here is a great post, mostly writen by fretlessbass and slightly modified by me, that explains compression basics very nicely.
