Why these settings

The Katana-Air has no physical presence control, so top-end bite is shaped directly with Treble at 7 on the Brown amp type. To replicate Daron Malakian's Dual Rectifier thump on desktop-sized stereo speakers, bass is raised to 7 while mids are pulled down to 4 for the iconic nu-metal scoop. The humbuckers on your SC-Custom II deliver sufficient output, requiring gain set to 7 to retain articulation during fast drop-C downpicking.

PRO TIPTune to Drop C (C-G-C-F-A-D) and dig into the strings right over the bridge pickup with a heavy pick (1.0mm+) using aggressive palm muting to lock down the percussive stop-start staccato rhythm.
