Double Drive 3X with a factory Private Stock Modification. The MOD gives you more aggressive hard rock and metal tones rather than classic, bluesy-style tones. It features a tighter low end and a wider Level taper.
Our friend, Tristan Avakian, takes it for a spin.
This MOD will be available at no additional cost for a limited time.
