Why these settings

Orange Crush 20 has no mid control and runs hotter than the Matchless clean platform used on the recording. Gain is kept low at 3 to preserve shimmer and prevent breaking up. The neck humbucker on your AZ2402 with tone rolled to 8 approximates the ES-325's warm semi-hollow voice. Studio reverb was added in post, so your dry signal is correct for tracking.

PRO TIPLet notes ring and overlap—Caleb's phrasing on this track relies on natural sustain and space between phrases, not attack. Pick lightly near the neck pickup for maximum bloom.
