Product Details
Precision Intonation. Classic Cornet Voice.
The Aurosus AU-ACR-8358S is a silver-plated Bb cornet with a double trigger system and stainless steel piston valves, designed for student and intermediate players who demand precise intonation control in school band, brass ensemble, and solo performance settings. The double trigger configuration — covering both the main tuning slide and the 3rd valve slide — allows real-time pitch correction on the fly, without stopping to manually adjust slides between phrases.
Key Features
- Double Trigger System — Main tuning slide trigger and 3rd valve slide trigger enable real-time intonation correction on low D, C#, and other problematic pitches; essential for ensemble playing and audition preparation
- Stainless Steel Piston Valves — Corrosion-resistant, smooth valve action that maintains consistent response through years of daily practice without sticking or sluggishness
- Silver-Plated Brass Body — Bright, professional appearance with corrosion-resistant surface protection; silver plating is preferred by many school band programs and ensemble players
- Hand-Crafted Soldering — Precision-engineered joints ensure airtight construction and consistent tone response across all registers
