ConsTest was hugely appreciative of the support received from Mercer & Barker in 2023. Mercer & Barker sponsored the Best Euphonium prize. In 2024, Mercer & Barker sponsored the Best Bass Section and the Best Euphonium prize. 

“Mercer & Barker Ltd was created as a company and launched in the Autumn of 2019 and is the brainchild of Carl Mercer and George Barker, a collaboration of two Tuba players and friends striving to design, develop and create brass instrument mouthpieces of the highest quality using the best of British precision engineering.

These mouthpieces are not only aesthetically pleasing but have been developed and designed to improve core sound, adaptability and secure intonation across all registers. Working with our customers we offer many bespoke finishes which only enhance the look of our product and meet their personal requirements.”
