I played with it a bit, but couldn't turn the treble down enough... 
Also, turning the bass up by playing with the filter frequencies led to 
massive distortion.

If there is a gui I'd like to know about it.  People on the subway look 
at me funny when I whip out my laptop to set the volume. :)  Also, I'd 
like to steal some code from it...
