Compressor Confusion

Hey guys and girls, I'm not sure if this is a really stoopid ? or not but here goes-*** is a compressor? Or more exactly, what's it supposed to do for me? I bought one off ebay the other day (a Carl Martin Comp/Limiter) and aside from increasing my signal level, and changing how long a note sustains, I can't seem to get any other change from it, yet every bass player I've met swears by them. I play a Fender Mike Dirnt signature P-bass with SD Vintage pickups, through an Ashdown ABM 500 EVO11 and an ABM410t cab. I mainly play rock/blues/60s,70s and 80s pop fingerstyle, and I don't use any other effects. Thanks for reading my ramblings...
 
There are several threads about this, so use the SEARCH function. Besides, there are very understandable articles on the net, like:

A brief definition is that compressors limit the dynamical behaviour of a signal, this meaning, it reduces excessive peaks or makes low volume signals louder (or both at the same time). Hope these articles help. Good luck!

Yup. That's about all a compressor does in very simple terms,..... but for a bass player (especially playing rock, blues, funk, etc.) it can make a really good difference. It keeps your sound up front inthe studio and on the stage by decreasing dynamics and putting the bass in yo face.

You bought something on E-bay without knowing it's purpose? :hmm:
