Straight Bulb Horn 2 1/2″ bell, 17″ length. Brass bulb horn with removable reed and bulb. Uses a bulb with a 5/8 inch fitting. You should expect your brass instruments to have, or develop an attractive antique patina. However, if you prefer the high shine look we recommend Brasso as a good polish. Mideast makes this instrument with love and hard work to make this instrument best.
