Why these settings

The Marshall MG30CFX is set to its clean channel with gain dropped to 2 so the Behringer HD300 acts as the dedicated high-gain preamp without muddying the signal. We push Bottom and Tone on the HD300 while scooping the amp's mids to 2 to recreate the iconic Mark IIC+ graphic-EQ V-curve. Note that the MG30CFX lacks a physical presence control, so top-end bite is driven via the treble and pedal tone knobs. Clean intro: bypass the HD300 pedal and roll guitar volume to 7.

PRO TIPStrict, aggressive downpicking with the side of your picking palm locked firmly against the bridge saddles is essential to match the dry, percussive chug of the Justice tracks.
