AB Bow Rosin for Violin, Viola, Cello
AB Bow Rosin for Violin-Viola-Cello is a dark rosin. In the late 1800's, Miss Amy Birch (AB) cultivated a rosin for her own personal use. After many long examinations, she built up a compound which was 'kind to the bow,' unaffected by limits of temperature or humidity. In light of it's non-obstructing attributes, her new rosin delivered volume and purity of tone. It was first commercially showcased in 1896, at the command of Miss Birch's professional colleagues.
