Why these settings

The Katana 50 MkII lacks a physical presence knob so high-frequency bite is shaped directly with Treble at 7 on the Brown amp type. Engaging the onboard Screamer boost with zero drive and high level replicates the TS9 pushing the modded Marshall front end, tightening the low-end flub. Keeping Mids at 7 ensures the signature early thrash cut without modern mid-scoop hollows.

PRO TIPStrict all-downstrokes on the iconic main riff with heavy palm-muting right against the bridge saddles is essential to get the sharp, percussive attack heard on the record.
