The beauty of the RAT2 lies in its versatility.  Used as a primary distortion, it excels at arena rock rhythm tones and soaring leads.  Do you have a powerful amp with too much headroom for the gig?  Let the RAT2 be your dirty channel.  Maybe you already love your amp’s distortion.  Use the RAT2 as a boost for solos and get the extra kick you need.
The RAT2 features the legendary RAT filter control.  Turn it to the right to roll off brittle high-end frequencies.  Having trouble cutting through the mix?  Turn it to the left and allow the natural brightness of your instrument to shine through.
