Hey people, can someone explain to me what a Dyna Comp or any other compressor actually does? How does is affect your sound/tone/any other effects being used?

I'm a classically trained guitarist who recently ventured into electric territory...now I feel like a noob again.

Thanks for any help.
It basically squashes your signal, evens out peaks and valleys in volume. And contrary to popular belief, it doesn't really add sustain.

Cheap amps are "that bad". They suck up your tone like cocaine at Kate Moss' party.
