Berg Larsen Tenor Sax Steel Duckbill 105

I came to the Berg Larsen Tenor Sax Bronze Bullet 100 looking for a metal mouthpiece that would push through a loud band setting without feeling like I had to force air. My background is in gigging and studio tenor work, and I wanted something with bite, clarity and a surprisingly musical center when I backed off the volume.

First Impressions

The Bronze Bullet 100 immediately impressed me with its weight and polish - it feels substantial in the hand and the bronze finish is highly reflective and resistant to quick tarnish. When I first put it on the horn the response was open and immediate, and I noticed right away that the piece carries top-end harmonics without sounding thin.

Design & Features

Construction-wise the Bullet is a cast bronze metal mouthpiece with a spherical "bullet" style baffle and a round chamber - the 100 designation corresponds to a tip opening in the medium range. It ships with a ligature and cap and has a polished, hard-wearing finish; the biting surface is fitted with an insert - traditionally grained ebonite - which gives a familiar contact for the reed. The facing comes in SMS (shorter European) or M (longer) options depending on the exact submodel, so check facing when you order.

Playability & Usability

With a medium tip opening and a low-to-medium baffle, this 100 felt free-blowing across registers - I could get big sound with modest air speed and still play softly without excessive harshness. Articulation is clear and fast, and double-tonguing patterns felt natural; I did have to experiment with reeds - I landed on a slightly harder reed than I normally use to tame the brightness and center the pitch. Getting a comfortable embouchure with this piece is straightforward, but intonation can vary depending on octave and reed choice, so expect to spend a little time dialing it in.

Real-World Experience

I used the Bronze Bullet 100 in rehearsal and a couple of louder gig situations where projection was essential, and it delivered reliably - the midrange cuts nicely and the top end gives a brass-like edge that sits well over drums and amplified instruments. In a studio setting it recorded with bite and presence, though I had to be mindful of sibilance on certain mic placements; backing off the attack and using a slightly darker reed helped maintain warmth while preserving clarity. On ballads I found the tone could be tamed into a pleasing, round sound if I focused on slower air and reed choice, which surprised me given the piece's reputation for brightness.

The Trade-Offs

The trade-offs are the usual ones with bright metal pieces - you get projection and edge, but you also have to manage brightness and intonation, especially in the upper register. The mouthpiece is heavier than ebonite alternatives, so it changes the instrument balance slightly and could tire the neck with long sessions if you’re sensitive to weight. Finally, quality control on Berg Larsen pieces can be variable if you buy used, so I recommend buying new from a reputable dealer or testing in-person where possible.

Final Verdict

The Berg Larsen Tenor Sax Bronze Bullet 100 is an excellent choice if you want a metal mouthpiece that projects, adds bite, and sits well in aggressive ensemble contexts while still allowing musicality at lower volumes. I’d recommend it for gigging tenor players and studio musicians who need presence and edge, but less so for players seeking an ultra-warm, dark jazz sound without experimentation on reeds and mic technique.
