I would suggest eschewing any expectation of elite engineering with this type of music.
Late-1920s-through-mid-1960s recordings of Blind Lemon Jefferson, Son House, Blind Willie McTell, Charley Patton, Huddie Ledbetter, Blind Willie Johnson, Mississippi John Hurt, Robert Johnson, Skip James, Reverend Gary Davis, Mississippi Fred McDowell and others are the cream of the crop. Recording quality ranging from rough to acceptable.
If I could have a fast food chain (Stevie Ray Vaughn, Joe Bonamassa, Eric Clapton) or real Mexican food, I’ll take the real deal any time.
No amount of slick audio engineering can transform a pretender into a contender.
