Aubert Mirecourt Double Bass Bridge #21 – 138mm ‘Belgian’ (Treated)

The Aubert Mirecourt #21 Belgian is a high-grade bridge blank specifically designed for 3/4 size double basses. Crafted from select French maple, this bridge features the Belgian pattern, known for its elegant, slender geometry and higher "heart" placement. This design is favored by players looking for a more articulated, focused sound with enhanced clarity in the upper registers. This model is treated, meaning the wood has undergone Aubert’s specialized seasoning process to improve resonance and long-term structural stability.

Angkor Music Luthier Insight

The Aubert #21 Belgian is an excellent choice for 3/4 basses that benefit from a brighter, more "soloistic" tonal profile. At 138mm wide, it provides the correct footprint for most standard 3/4 instruments, ensuring the bridge feet sit directly over the bass bar for efficient energy transfer. Because it is treated, the maple is more resilient to the immense downward pressure of bass strings, helping to prevent the bridge from warping or "leaning" over time. The 193mm height provides ample material for your luthier to achieve a perfect action for your specific playing style.

Professional Setup Required

This is a bridge blank. A professional luthier must carve the feet to match the arch of your bass and shape the top to the correct string height and curvature for your instrument.

Frequently Asked Questions

What are the benefits of the Belgian pattern on a bass?
While French bridges are often chosen for warmth and roundness, the Belgian pattern is typically leaner. This reduces the mass of the bridge, allowing the bass to speak more quickly and providing a bit more "bite" and clarity in the upper register.

Why should I choose a "Treated" bridge?
The treatment process essentially ages the wood artificially. It makes the maple slightly drier and harder, which not only improves the clarity of the sound but also makes the bridge more physically stable against the changing humidity and high string tension.

How do I know if 138mm is the right size for my bass?
138mm is a standard width for 3/4 instruments. To verify, your luthier can measure the distance between the center of your bass bar and the soundpost to ensure the bridge feet will sit symmetrically over the internal supports.
