Why these settings

The Yamaha THR10II LEAD model emulates the British Plexi crunch with the variac sag necessary for the Brown Sound. To compensate for the brighter single-coil pickup in your Fender Player Strat compared to Eddie's bridge humbucker, keep the amp treble at 5 and roll the guitar tone knob back to 8 to tame high-end harshness and thicken the midrange harmonics. Use the THR's onboard phaser set to a slow rate and built-in hall/plate reverb to capture the iconic Sunset Sound acoustic space without needing external pedals.

PRO TIPHit the strings aggressively near the bridge with the edge of a heavy pick to trigger maximum upper-harmonic sizzle and pinch harmonics on the fast tremolo-picked runs.
