Why these settings

The Katana's Clean amp type gives the ultra-clean headroom of the studio Roland JC-120 track. Your passive Quantum neck pickup matches the round warmth of Hetfield's EMG 60; rolling the guitar tone back to 9 removes harsh string bite. The Katana 50 MkII has no presence knob on its panel, so clarity is balanced using Treble at 5. Heavy solo section: switch to Lead amp type with Gain at 7 and Boost on.

PRO TIPPluck the open strings firmly with the flesh and side of your thumb rather than a pick to get that full, soft transient response heard on the intro track.
