Here's a sample of the new Amptweaker TightMetal JR from January NAMM 2016 in Anaheim. It features two players with very different styles and metal tones, so I think it shows off how well the pedal adapts. First is Kiyoé-Krista Fluker, guitarist with the LA based metal band Harlequin, and then Jason Frankhouser, guitarist with Austin's Course of Ruin. For more info, go to amptweaker.com.
