Why these settings

The Katana 100 MkII Brown channel replicates Randy's cranked Marshall JMP, while the pushed mids compensate for his famous MXR 10-band EQ 500Hz-800Hz hump. Using the Katana's onboard Booster block simulates the MXR Distortion+ hitting the front end without needing external pedals. Your Epiphone Les Paul bridge humbucker matches his Gibson Les Paul Custom attack closely.

PRO TIPPick aggressively near the bridge with a stiff pick to reproduce Randy's signature sharp percussive attack on the F#m riff.
