Why these settings

The Champion 50XL's '65 Deluxe voice emulates Blackface clean headroom, perfectly matching Mayer's Two-Rock/Dumble platform. Gain is dialed to 4 so hard picking introduces subtle tube-like grit while remaining glassy clean on soft strokes. Note that presence is omitted as the Champion 50XL faceplate does not feature a presence knob.

PRO TIPPluck the rhythm chords using the flesh of your thumb and index/middle fingers rather than a pick to replicate Mayer's rounded, percussive attack and dynamic bloom.
