The other day I was at Sam Ash with a friend of mine that wants to learn how to play.

I was showing off with pedals and found a pretty good combination of Boss pedals. They were the Boss Blues Driver and the Boss Compression/Sustainer CS-3.

The sound was OFF THE CHAIN!!!

Anyhow, I think my Bad Monkey is a better "blues driver" than the boss so Ive got that aspect covered.

Now heres my quandary, Ive got a compression setting on my Behringer GMX 210.

What if any is the difference between a regular compressor and the boss CS-3? I can hear the sound being compressed by my amp but it doesn't produce the same kind of sustain as the boss pedal.

I can play with the variables on the amp and there is a fast and slow compression rate. It would be greatly appreciated if someone could explain the difference between fast and slow compression.
