Dave I sing all of the night and I leave really only use drum bass and rarely much else, but I really find the regs great to balance the volumn between different drums etc ---lyrics to list songs is great.There is a big difference in vols and as I go from style to style occasionally I find regs great. I am glad that the topic is coming up a bit lately as I was lonesome for the past two yrs waiting for someone to use regs on HD. Pierce
