Why these settings

The Katana's Clean channel approximates the Twin Reverb's headroom and clarity. Your Silver Sky's single coils match the original Strat tones perfectly—no compensation needed. Mid pushed to 6 because the Katana Clean is slightly scooped compared to a real Twin's natural midrange warmth. Tone knob rolled to 7 to tame the Silver Sky's bright overwind and match the warmer studio sound.

PRO TIPPick closer to the neck for that soft, rounded attack heard on the record—the electric guitar parts are meant to blend with the acoustic, not cut through. Use your fingers or the fleshy part of the pick for extra warmth.
