Improvising over a backing track with the Dumble amp model of the Axe-Fx III, firmware Cygnus beta 11. The backing track was recorded last year, it was a post-rehearsal jam. I muted the guitar track I played back then. It's from a song called "Une dernière fois encore", by Canadian singer Garou. Not the easiest chord sequence to improvise over, at least for me, but I love it !
