Hi, I read recently an interview of Bob Moore where he said that Joe Zinkan overdubbed the slap on Johnny Cashs "Boom Chicka Boom" album. I've never thought of that before... What do think of Farons song? Have they already overdubbed the slap in 50's? I'm just wondering because on some parts of the song the slap has that constant shuffle drive but the rhythm of the tone is something like 1xhalf + 2xquarters. I mean they overdubbed a lot but the tones are really short so he might mute the strings to slap the shuffle... What do you guys think?
