Since you are playing a 6-string Ibanez RG550 into a Mustang LT25, the 'Metal 2000' amp model delivers the tight, high-gain saturation and scooped voicing characteristic of the Justice production without needing the DS-1. The Mustang LT25 faceplate has only Bass and Treble controls (Mid and Presence are null), so Treble is boosted to 7 to replicate Newsted's metallic clank while Bass is kept at 5 to prevent low-end mud through the 8-inch speaker. The bridge humbucker with the tone knob wide open ensures the aggressive snap of the riff cuts through accurately.
