Why these settings

The Davis GM-25 is an entry-level practice amp without the preamp saturation needed for Dimebag's intense Randall solid-state crunch, so the Boss DS-1 acts as your dedicated high-gain engine into the clean channel. Setting the DS-1 Tone to 7 and Dist to 9 recreates the razor-sharp bite and sustain of the Bill Lawrence L500XL and parametric mid-cut EQ. The amp EQ is severely scooped with mids at 2 and treble pushed to 8 to match the aggressive Pantera frequency profile. Clean intro/outro: bypass the DS-1 and add a touch of chorus or light delay if available.

PRO TIPDimebag's attack comes from aggressive, ultra-precise right-hand alternate picking right against the bridge saddles with a heavy pick, keeping the palm muting ultra-tight to preserve the scooped percussive chug.
