Why these settings

The Katana's Brown amp type emulates a hot-rodded Marshall circuit with strong low-end and midrange bite. Because the LTD EC-1000 features higher-output humbuckers than Slash's vintage-voiced Alnico II pickups, keeping the gain at 6 prevents over-saturation while maintaining authentic punch. The presence control on your Katana 100 MkII adds the necessary high-treble edge to mirror a cranked Marshall power section.

PRO TIPDig in hard with a heavy pick near the bridge saddles to get the sharp percussive attack and harmonic bite characteristic of the main riff.
