Since the beginning, it has been a goal of ours to provide premium instruments for left-handed players. This Thunderhorse is the first-ever McGrath Guitars lefthanded bass available for purchase. Built as a showpiece for NAMM 2026, this is a rare opportunity to own a world-class instrument with a classic aesthetic and modern performance. The price will be in line with right handed models after Namm.
