The magnificent Otis Rush shows how it’s done in this instrumental clip as he handles a fairly non-traditional tandem of right-handed Epiphone Riviera, played upside down and not restrung, straight into a Vox AC-30 at low volume.
Rush gets fine backing from of Little Brother Montgomery on piano, Fred Below on drums and Jack Myers on bass. This was a stop on the American Folk Blues Festival tour of Europe and likely from October 1966 at Friedrichstadt-Palast in Berlin, Germany.

Man, I’ve never hear Otis swing like that! I’m mostly familiar with his playing on slow blues & shuffles. Great tone as well.
