As I look around for good examples of DBX in songs, there’s certainly a lot of bluegrass, as well as songs that would otherwise be played fingerstyle (i.e. pattern songs), typically on acoustic. The kind of slower/moderate tempo jazz that really spotlights guitar seems to have some DBX going on, too.
Got to admit that I’m not so broad genre-wise, and that’s hampering me a bit here. Where else could I look for tunes with a lot of DBX?
