Just to be clear, this is a graphic EQ- the bands are fixed. That said, it is still an amazing unit. This is a stripped down model from Nightpro's EQ3 which is a 2 rackspaces and black colored. Pro's- the air band is unbeatable. What Nightpro did is design their curves so shallow that there is practically no phase distortion with the EQ. This means that boosts are incredibly wide but it also means that you can crank things without much harshness. Cons- lack of headroom, more of a pinched/brittle sound than the EQ3. I think this could be fixed with a mod however.
