Nelson amplifies the presence of the main guitar in the mix by applying two key adjustments to a supporting synth track: widening its stereo image and subtly reducing its low-mid frequencies.
These changes carve out a spacious backdrop for the guitar, ensuring it stands out with greater clarity. The widening relocates the synth to the mix's outer edges, enhancing the stereo field, while the EQ cut prevents the synth from masking the guitar's tonal body.
