This is the bridge heard on the recordings that defined the sound of a Burst.\u003c\/p\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:align-top\"\u003eGetting an ABR-1 right isn’t about appearance — it’s about mass, alloy, and fit. Original bridges were die-cast from zamac, a zinc-based alloy with specific resonant characteristics, and fitted with soft brass saddles that sat loosely in the bridge body. This allowed the assembly to subtly move and “breathe” with the guitar, contributing to a more open and responsive tone.\u003c\/p\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:align-top\"\u003eThe saddles themselves were made from soft brass. The thumbwheels were thin and also made from soft brass. And notably, there was no retaining wire on Burst-era bridges — that feature was introduced later in the early 1960s. This bridge remains true to that original wire-free design.\u003c\/p\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:align-top\"\u003eAfter decades of studying vintage examples, St. Helens selected a standout original bridge and submitted it for laboratory analysis. Using that data, a custom alloy was developed to match the composition and hardness of the original as closely as possible. The result is a bridge that not only looks correct, but responds and resonates like the real thing.\u003c\/p\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:align-top\"\u003eEach unit is drum and hand polished for an authentic vintage appearance, with attention given to every detail of fit, feel, and function.
