Schwartz x RetroSpec St. Helens ABR-1 - Nickel

Introducing the Schwartz x RetroSpec Collaboration. All parts are aged by Historic Makeovers.

The St.Helens ABR-1 Bridge is made from our unique alloys, analyzed from original parts to meet vintage correct specs regarding composition and hardness to make up for a truly original and authentic sounding hardware.

After studying various vintage original bridges over the past two decades, we selected what we believed to be the best-sounding one and sent it to a laboratory for a precise material analysis.
The data and insights we gathered enabled us to custom order a unique alloy from a local supplier, available exclusively for Schwarz Custom Parts. This allows us to cast our parts to precise specifications and measurements.
