Why these settings

The Lekato JA-05G is a compact plug-in practice unit with standard Gain, Tone/Treble, Bass, and onboard Reverb/Delay without dedicated midrange or presence controls. To emulate Eddie's cranked Marshall Super Lead, use the high-gain Drive/Distortion mode with Gain pushed to 8 and Treble at 7 to capture the signature upper-mid harmonic bite. Keep Reverb around 5 to simulate the Sunset Sound plate reverb depth.

PRO TIPPick hard near the bridge with the edge of a heavy pick to bring out the aggressive pinch harmonics, and use the fleshy side of your picking hand's index finger to tap cleanly over the fretboard wires.
