Trevor James GR Grenadilla Piccolo - High WaveThe latest addition to the TJ flute family is a very free blowing TJ Grenadilla (African Blackwood) piccolo with silver plated mechanism. High Wave headjoint: A Wave headjoint profile is carved with a slightly higher front wall & lower back wall for easier control over dynamics and a more focused lower register. The High Wave features an even higher headjoint front wall which deflects a greater amount of air, resulting in a freer blowing experience.
