The Selmer Sigma Model 1905 trumpet features a unique "concave bore" leadpipe. This leadpipe allows the player to put in a good amount of air due to the open SELMER 1905 start of the leadpipe. This larger amount of air is then quickly compressed giving more focus and power to the air column. It is a classic design, with a lacquer finish over brass. Comes with case, mouthpiece and cleaning products. It is a professional level trumpet with a wide tonal palette available to the experienced player. Great valve action, easy to play, and a beautiful tone.
