Weelittledrummer wants "a big, sexy guitar sound." Anything can be big, but sexiness is confined to the living.
Thus I believe that the recording equipment may do "big", but "sexy" is a matter of musicianship. Musicianship would include selecting, as mentioned, the right guitar, strings, picks (if any) and articulation.
They are not thick on the ground, but what I think you are yearning for is a Kamourska Etude guitar.
