also, something else i have noticed with my empeg - there is a puzzling shift of volume from 'centered' over to the left hand side, whenever i shift my Q of any frequency down to 0.01 - in fact, if you sit still and twirl the Q setting up and down you can hear the midrange output (mainly from vocals to the highs) shift over to the left.

This is a known bug in 2.0 beta 11. If you mess with the Q in the 2.0 beta 11 equalizer, it's only working on one of the two channels. The other channel gets its Q set to some arbitrary value (either minimum or maximum I don't remember). This will be fixed in the next release.

Note: 1.03 does not have this problem, and there is no problem in 2.0b11 if you use the auto Q. Also, if you set the left and right channels independently, it works correctly. This is only in locked L+R mode and only when you independently adjust the Q.
