DETAILS
Elevate Your Performance with the AUROSUS 504D Bass Trombone
Designed for intermediate players ready to upgrade their sound, the AUROSUS 504D Bass Trombone combines professional-grade engineering with unmatched versatility. Whether you’re mastering jazz ensembles, orchestral performances, or contemporary compositions, this trombone delivers the rich, resonant tones and precision control that serious musicians demand.
Why This Bass Trombone Stands Out:
✅ Pro-Level Sound & Playability
Featuring a 10" yellow brass bell (254 mm) and L 14.3 mm (0.562") bore, this trombone produces a bold, projecting sound with exceptional warmth. The inline open-wrap valve system ensures smooth airflow and seamless transitions across Bb/F/Gb/D tunings, perfect for tackling complex arrangements.
✅ Premium Build for Lifelong Durability
Crafted from high-quality brass with a high-gloss lacquer finish, the 504D resists wear while maintaining its lustrous appearance. The chrome-plated nickel silver inner slides and alpaca outer slides offer buttery-smooth action, reducing friction for lightning-fast technical passages.
✅ Complete Ready-to-Play Package
Includes the original Vincent Bach 1½G mouthpiece – a favorite among professionals for its balanced resistance and tonal clarity – plus a lightweight backpack case with ergonomic straps for hassle-free transport to rehearsals, gigs, or competitions.
✅ Engineered for Growth
With its adjustable hand rest and wide mouthpiece shaft, this bass trombone adapts to your evolving technique. The additional Eb/G slide (included) lets you experiment with extended techniques, making it ideal for players transitioning to advanced repertoire.
Technical Excellence in Every Detail:
- Valve Type: Inline Open Wrap
- Bell Material: Yellow Brass (254mm/10")
- Slide Configuration: Nickel Silver Inner/Chrome-Plated Outer
- Finish: High-Gloss Lacquer for Enhanced Resonance
- Case: Padded Lightweight Backpack Design with Slide Grease
Who It’s For:
• Intermediate players seeking trombone upgrades with pro features
• Educators needing a reliable instrument for student development
• Gigging musicians valuing portability without compromising sound
The AUROSUS Promise
Backed by rigorous quality control, the 504D bass trombone merges Bach-level craftsmanship with modern affordability. Its open-wrap valve design and premium brass construction ensure you’ll stand out in auditions and recordings alike.
