According to Wikipedia, on “Let It Bleed”:
“According to some sources “Country Honk” was recorded at the Elektra recording studio in Los Angeles.”

“Other sources state that “Country Honk” was recorded at Olympic Studios right after “Honky Tonk Women”, with only Berline’s fiddle part overdubbed at Elektra Sound Recorders Studio”
