The Katana 50 MkII uses the Brown amp model to replicate the saturated British-voiced CAE/Marshall rack tone, with presence set to null since the 50W panel lacks this control. To compensate for the Harley Benton JA-60's single-coil P90 pickups compared to Mustaine's high-output Seymour Duncan JB humbucker, bass is pushed slightly to 5, treble kept bright at 7 for bite, and gain set to 7. Keep the built-in boost off to preserve tight, articulate thrash palm-mutes without flubbing the low end.
