Why these settings

The Katana 50 MkII Brown voicing provides the heavy British Marshall/Orange hybrid saturation Ghost uses. We use the SD-1 as a light boost (high level, low drive) to cut flubby sub-bass and push the 1kHz mid punch without muddying the amp. Presence is null because the Katana 50 MkII panel lacks a physical presence knob.

PRO TIPGhost tunes a full whole step down to D Standard (D-G-C-F-A-D); tune your Ibanez down to get the exact low-end string tension and chug of the opening riff.
