The Atrum Diurum is a high gain motherf*%@r and no mistake. Of great note is the clarity it maintains, even at highly saturated levels. With sufficient distortion to melt face and other body parts the Atrum Diurm still delivers clarity and definition of every string, even with the most complex chords. With low end resonance to compliment drop tunings coupled with a mid-scoop filter, this pedal dials up great tones from classic Heavy Rock to Extreme Death Bloody Metal!
