A Vintage Look Meets Modern Playability

Designed in conjunction with French professional trumpet player Christian Martinez, B&S's MBX3 Heritage trumpet evokes the utmost confidence and class. With luxury appointments like a hand-hammered/1-piece bell, monel pistons, and a gorgeous brushed gold lacquer finish, this eye-catching trumpet is well suited for the discriminating professional. Its redesigned 0.459-inch medium-large bore promotes stable and efficient airflow while its bodacious 4.803-inch gold brass bell allows your sound to resonate while projecting it to the farthest corners of the concert hall. Still, the MBX3 is good for more than just look and feel — each of its carefully crafted features contributes to the horn’s overall versatility, offering impeccable tuning accuracy and stable tone that helps players blend their sound with any ensemble or genre, ranging from jazz to classical.

Approachable, user-friendly design

Despite its intimidating appearance, B&S says the MBX3 is user friendly, and musicians at Sweetwater earnestly agree! On the surface, there's nothing to the MBX3's core design that appears different than any other professional trumpet. So what makes it different? Although practically unnoticeable, a completely redeveloped bore design gives the MBX3 outstanding tuning precision and airflow. Paired with rugged and reliable corrosion-resistant monel pistons, players are sure to adapt to the MBX3 almost instantly.

It's all in the details

The MBX3 wouldn't sound as good as it does without the care B&S takes to hone the smallest details. That's why its 4.803-inch gold brass bell just sounds better than others with the same description — B&S has combined an improved 0.459-inch bore with a hand-hammered/1-piece gold brass bell to give players greater stability across the trumpet's range. On top of that, the MBX3 features standard water keys and a brushed gold lacquer finish that merges a slightly antique look and timbre with modern playability, putting the MBX3 in a league of its own.

B&S: manufacturing high quality brass instruments for over 250 years

Blechblas und Signalinstrumenten — better known as B&S — is a long-standing instrument manufacturer with over 250 years in the business.
