Why these settings

The DSL40CR's Ultra Gain channel nails the Rectifier's saturated aggression better than its crunch channel. Mids dropped to 4 to approximate the Rectifier's scooped voicing — the DSL is naturally mid-forward, so pulling mids back prevents honk. Treble at 6 instead of 7 because the DSL's EQ center is brighter than a Recto; presence matched at 6 for cut without fizz.

PRO TIPPalm-mute hard and pick closer to the bridge for that percussive, staccato attack Malakian uses — the tone is tight and gated-sounding, so let your picking hand do the work rather than relying on sustain.
