Why these settings

The Mustang LT25's British 80s model approximates the Marshall Plexi voicing. Your Epiphone's humbuckers are hotter than EVH's single Super Distortion, so gain is set to 8 instead of maxed — the original's Variac'd amp had a spongy, compressed saturation that high gain on a solid-state modeling amp won't replicate, but this gets the harmonic richness. Treble pulled to 6 (original was cranked) because the LT25's digital treble can get fizzy where a real Plexi stays smooth. Mids pushed to 8 to capture that mid-forward bark. Tone knob at 7 tames the Epiphone's brightness to match the warmer Frankenstrat voicing.

PRO TIPEVH's touch dynamics are everything — dig in hard for the aggressive pick attack sections, then lighten up for the legato tapping runs. Roll your guitar volume to 7-8 during the melodic intro for a cleaner, more vocal tone, then slam it to 10 when the tapping begins. The brown sound lives in how you hit the strings, not just the knobs.
