The Bach Stradivarius model 189XL in Eb/D trumpet has a vivid yet broad tone well suited for symphonic and solo repertoire. The 4-13/16" long one-piece hand-hammered yellow brass #239 bell provides a lighter more vibrant sound while the reverse tuning #25R mouthpipe and .462" bore has an open feel. The 1st slide thumb saddle make for easy intonation adjustments while the Monel pistons provide smooth quick action. The silver-plate finish provides a controlled brilliance to the overall sound. The 189XL has an extra set of slide for the key of D making it a very versatile instrument.
