Why these settings

The Ross RG-25 is a basic solid-state practice amp with limited gain and a flatter frequency response than the original tube Marshall. Pushed mids to 8 to compensate for the amp's lack of natural mid-forward tube character. Your Epiphone's humbuckers are warmer and higher output than the original P-90, so bass is cut to 4 to prevent mud—the P-90's raw spike came from its single-coil-adjacent clarity. Gain at 7 maxes out the available crunch on this amp; the tone will be thinner and less saturated than the original, but this is the closest honest match without pedals.

PRO TIPUse aggressive, committed downstrokes locked with the beat—the Green Day punk sound relies on precise rhythmic attack, not loose strumming. Dig in hard with your pick near the bridge to add harmonic bite that compensates for the amp's limited gain structure.
