The silver medal for workmanship went to Trevor Davis, Sam Morel and Gian Pangaro.

The silver medal for tone went to Benjamin Joella and Jacob Stone Pembelton. Pembleton also received a certificate for workmanship, along with Frederick Boissonnault, Benedict Puglisi and Mason Weedman.

Boissonnault and Weedman also received certificates for tone, while the convention favourite was awarded to Joella. Honorable mentions went to Andrew Hassel and Morel.

Competition basses were played from behind a curtain in the sound-off event, and voted on by the audience. The top five basses of the sound-off event were from Christopher Gutierrez, Sam Morel, Keiran O’Hara, Gian Pangaro and Gary Upton.
