01Katana Built-in Booster (set to Mid Boost or Treble Boost)
Simulates the cocked wah mid-range honk — engage the built-in Booster via Tone Studio and set to Mid Boost with level at 50%; this adds the nasal 1.5-2kHz peak of Slash's fixed wah position
02Katana Built-in Delay
~420ms delay time, 3-4 repeats, 15% wet mix — adds ambient depth without cluttering fast runs
Your Ibanez GIO has hotter ceramic humbuckers vs Slash's lower-output Alnico IIs, so gain stays at 5 instead of the original's amp-driven 4-5 — this compensates for the pickup output difference. The Katana Air's Brown channel voices Marshall-style mids; mid is pushed to 6 (vs typical 4-5) because the Katana's Brown voicing is slightly more scooped than a real Silver Jubilee. Rolling your tone knob to 6 is critical for the 'woman tone' vocal quality on the intro and solo.
