Bigsby® B3 Vibrato Tailpiece from the Original Kalamazoo Line, expertly sand cast from aluminum. This beauty weighs in at an ultra-lightweight 296 grams (that's just 10.4 ounces) and measures 7 5/8” in length and 3 5/8” in width, making it the perfect fit for your high-flying solos. The B3 is commonly used with thin archtops to carved-top solidbodies including some Gretsch® Duo Jet™ models. The lack of a tension bar creates a shallower break angle over the bridge for a softer string feel.
