Why these settings

Angus Young's tone relies on a cranked vintage Marshall pushed just into aggressive crunch rather than heavy saturation. On the Katana 100 MkII, the Crunch voice with Gain at 5 accurately reproduces the dynamic power-amp breakup of his 100W heads without getting fizzy. Mid and Presence are pushed slightly to replicate the bite of the SVDS wireless preamp boost used during the Compass Point sessions.

PRO TIPHit the open E and A chords hard with an aggressive downward pick attack, but choke off strings instantly with your fretting hand—the punch of this riff comes from crisp dynamic space and zero reverb.
