Why these settings

The Mustang LT25's Metal 2000 model approximates a modern Rectifier voicing. Your Ibanez GRX70QA has medium-output humbuckers vs Kasica's hot Les Paul pickups, so gain stays at 7 rather than the original's ~6.5 to compensate for lower output. Mids at 4 (slightly scooped) match the Rectifier's signature sound, but not fully scooped — you need midrange presence to cut through. The built-in OD as a clean boost is critical for tightening the flubby low end that modeling amps can have on high-gain patches.

PRO TIPPalm mute directly over the bridge saddles, not further up the strings — the Rectifier tone on this track has extremely tight, percussive chugs that come from precise right-hand placement combined with the amp's silicon diode rectifier setting keeping the low end controlled.
