Sammy teamed up with Xounts on their incredible sound system with cool custom Red Rocker covers. And now Xounts is giving away 40 systems to celebrate 40 years of AC/DC’s "Back In Black". Most importantly the contest will help generate donations for MusiCares that will help support people in need. You know from The Circle Lockdown Session of "Whole Lotta Rosie" that Sammy loves AC/DC and this is a great way to help out our brother and sister musicians who need it right now.
