The popular design of the 180S Stradivarius 43 Bell Series Professional Bb trumpet is combined with the #43 taper bell that has a slower taper to produce a brighter sound that is more brilliant and open than the standard #37 taper. The 180S43 also features a #25 standard leadpipe that offers some resistance that is effective in centering tone production. These two features combine to produce a trumpet that is well suited for jazz.
