Onboard subtle room ambience
The Spark 40 Plexiglas model nails the core Marshall crunch, while an onboard SAB Driver boost block replicates Jake Kiszka's signature treble-boost edge without causing digital clipping. Because your Epiphone SG already has the correct humbucker bite and mahogany resonance, keep mids and treble pushed to 7 to deliver the aggressive upper-mid bark heard on the track. The Spark 40 faceplate lacks a presence knob, so upper-register sparkle is handled directly via amp treble and the booster's tone control.
