Why these settings

The ID:Core 40 lacks traditional 3-band EQ and presence knobs, using Blackstar's single ISF control instead—turn ISF clockwise to 10 for British Marshall voicing. Use the Crunch voice with Gain at 6 to replicate Angus's cranked non-master-volume Plexi break-up without modern preamp fizz. Your Epiphone SG's bridge humbucker naturally matches the midrange bite of Angus's Gibson SG.

PRO TIPAngus gets most of his crunch from aggressive right-hand pick attack rather than amp distortion; strike the open E and power chords hard with a heavy pick near the bridge while keeping your left-hand muting razor-sharp.
