Why these settings

The NUX MG-300 lacks the natural compression and warmth of a real Mesa Mark IIC+ clean channel, so I pushed mids +1 and kept treble conservative to avoid harshness from digital modeling. Your Spectrum AIL-95 likely has ceramic humbuckers with bright upper-mids, so rolling tone to 7 and using the neck pickup compensates for the original's warmer Rickenbacker/Sadowsky single-coil voicing. The chorus and delay are doing the heavy lifting here—without them, this tone doesn't exist.

PRO TIPPlay with your pick angled slightly and use the fleshy part of your thumb near the strings for that soft, pillowy attack Wendy used—hard picking will kill the dreamy vibe. Let chords ring and overlap into the delay trails.
