The Bach Mariachi Trumpet LR190S43B ushers in a new era in the world of Bach Stradivarius. This marks the first time that bronze material has been used in the production of one-piece hand-hammered professional Bach bells.The LR190S43B features a lightweight body and two-piece valve construction that provides a quick response. The open feel of the reverse construction #25LR mouthpipe combined with the bronze material in the bell results in a very responsive, lively yet full sounding instrument. As beautiful to look at as it is to play, the LR190S43B is well suited for all types of music.Adorned with unusually ornate filigree across the bell, it is additionally apportioned with yellow brass (70% copper, 30% zinc) on the valve casing, and a bronze brass bell (90% copper, 9 1/2% zinc along with elements of tin). It is a 43-style bell, whose slower taper is quick and responsive, ideal for the fast, tight staccato of Mariachi music. It was designed in cooperation with Jose Hernandez, one of the world’s finest Mariachi players.In pianissimo passages, it offers a very soft, sweet sound, but when you put more air into the horn, it straightens out into a shimmering, brilliant, regal sound. If your trumpet playing requires dynamic range, change of mood and fast response to brisk tonguing technique. the LR19043B may be the ideal solution.Bach Stradivarius .459 Medium-large bore, tow piece valve construction #25LR mouthpipe, monel pistons, 1st slide thumb ring, adjustable reverse slide rod stop, vintage bracing and finger hook, deluxe engraving, clear lacquer finish, Bach 3C mouthpiece, C180M woodshell case with zippered cover.
