The A4 is one of the most popular models in the Adams trumpet line — a standout choice for soloists who want a rich, warm, and fluid sound with exceptional depth and character. Its large-diameter one-piece bell, heavy chassis, and unique flare design provide outstanding projection, a broad sound dispersion, and excellent feedback to the player.
Despite its weight, the A4 is remarkably versatile, delivering a full, colourful tone that adapts across a range of musical styles and settings. A result of extensive collaborative design, the A4 combines craftsmanship and innovation to offer players a trumpet that truly amplifies their musical voice.
