Why these settings

Your Epiphone SG's humbuckers are hotter and warmer than the original P90s, so I pulled treble down 1 and pushed mids up to 7 to retain the gritty, articulate bark. The Spark MINI's Crunch/Marshall-style model will get you closest to that raw 1974 studio breakup. Roll your tone knob to 7 to tame the humbucker's top-end and approximate P90 openness.

PRO TIPDig in hard with your pick near the bridge for that aggressive attack Hunter used on the intro solo — the dynamics of your playing create the sustain, not extra gain.
