John Mellencamp's Official Website
Used on No Better Than This, as stated in this August 16, 2010 Bloomington Herald Times article archived on Mellencamp's official website.
He’s never realized that ambition more than with “No Better Than This,” his 25th album. It’s 13 songs written and recorded over 13 days on a 55-year-old Ampex tape recorder using one classic RCA 77 DX microphone. The songs were all laid down on the road during off-days on his 2009 tour of minor league ballparks and off-the-beaten-path venues with compatriots Bob Dylan and Willie Nelson.
It is also mentioned in this August 17, 2010 Music Angle (now Analog Planet) article, also archived on Mellencamp's official website.
Equipped with John Mellencamp's then recently acquired vintage 1/4" reel-to-reel 1955 Ampex 601 mono tape recorder and a pair of iconic 50's era RCA ribbon microphones ( a 77 DX and 44 used singly) presumably supplied by producer T-Bone Burnett, the duo, accompanied by Mellencamp's wife Elaine, who shot the album's cover photo, hit the road during a break in last summer's Bob Dylan-John Mellencamp-Willie Nelson tour to record thirteen freshly penned songs Mr. Mellencamp had written over thirteen prolific days.
