Giddings Mouthpieces stands alone with the world's largest selection of stainless steel mouthpieces, crafted from the finest surgical-grade materials for unmatched durability, hypoallergenic performance, and superior energy transfer. The DJNV was created in close collaboration with renowned trombonist David Jackson, blending his expertise with our precision engineering to deliver a mouthpiece that rises to every challenge — from blistering highs to thunderous lows, and everything in between. This large bore tenor mouthpiece features a slightly more rounded rim contour for exceptional comfort and smooth feel, reducing pressure points during long sessions. It's also slightly heavier than many of our other tenor models — that added mass is no accident! It provides rock-solid stability, helping the mouthpiece hold its center when you're pushing the extremes of dynamics, range, and intensity that modern music demands. The result? A focused, resonant core that stays true under pressure, with effortless projection, crystal-clear articulation, and total control across the full register.

Why players everywhere love the DJNV:

• Unshakable stability in the extremes — Extra mass locks in the sound, preventing breakup when you need maximum power, volume, or dynamic contrast without losing focus.
• Comfortable, rounded rim — Slightly softer contour reduces fatigue and lip strain, letting you play longer with confidence in demanding rehearsals, gigs, or recordings.
• Versatile performance — Delivers a big, rich tenor tone with warmth and depth, while maintaining clarity and quick response for any style — orchestral, big band, jazz, or contemporary.
• Instant response & slotting — Secure attacks, smooth legato, and reliable slotting from pedal to altissimo, giving you the edge on tricky passages and exposed lines.
• Premium stainless steel construction — Hypoallergenic, no replating ever, maximum air-to-sound efficiency, and lifetime durability that outlasts plated alternatives gig after gig.
• Signature collaboration — Designed with input from David Jackson, this mouthpiece meets the real-world needs of players everywhere who demand reliability and expression under pressure.

This isn't just a mouthpiece — it's your reliable partner for tackling the most demanding music with authority, comfort, and control. Whether you're powering through a full orchestra, driving a big band section, or exploring new territories, the DJNV gives you the stability and presence to play with total conviction. Ready to hold the center and push your limits? This is the one.
