			Godspeed,
I am not very good at describing sound characteristics with words, however, I agree with bongonotbombs's  description of mellower with more depth and less ring.  Also, fewer overtones and more of a fundamental pitch.  
If you can hear the difference between water buffalo, mule and cow skin on a wood drum, I think you hear the same differences on a fiberglass drum.
