The Mighty 40BT is an unrecognized amp model so I cannot verify its exact voicing or control layout. Settings target the AC30's mid-forward chime: mid pushed to 7 compensates for your Ibanez's humbuckers which are darker and hotter than May's single-coil Tri-Sonics. Treble held at 6 to avoid ice-pick harshness from the humbuckers. Gain moderate at 5 because May's crunch came from the Rangemaster pushing a clean AC30, not preamp saturation. A treble booster pedal (TC Spark, EHX LPB-1, or actual Rangemaster clone) would get you significantly closer—run it into the amp's clean channel with amp gain at 2-3.
