Ty’s acoustic guitar sound

Ty always has the jangliest sounding acoustic guitar, and I was just wondering if anyone knows how he gets that sound on recording. I know he tunes whole step down sometimes and that adds some extra twang, but there’s something very full and buzzy about it that just doesn’t sound like most acoustic guitars I’ve heard in person. The sustain on chords is super long, but it doesn’t sound exactly like that super bright new-string sound. Definitely reminds me of the Beatles or older recordings like that. Is that a compressor on there? Certain kinda mic? Size of guitar body? Maybe he just has way better sounding guitars than me haha, I dunno. Just wanted to see if anyone here knows a thing or two about it.
