Aubert France #20 Etude Double Bass Bridge – 1/2 Size (Untreated)

The Aubert France #20 Etude is a high-quality bridge blank designed specifically for 1/2 size double basses. Crafted in France from select maple, the Etude series provides an excellent balance of durability and tonal clarity, making it the ideal choice for advancing students and school orchestral instruments. This French model features a traditional, robust geometry that supports a warm and full-bodied sound. Being untreated, this bridge remains in its natural state, allowing for a pure acoustic response and a traditional luthier fitting process.

Angkor Music Luthier Insight

The Aubert #20 Etude is our go-to recommendation for 1/2 size basses requiring a reliable, high-quality replacement bridge. At 136mm wide, it is perfectly proportioned for fractional-sized instruments, ensuring the feet align correctly with the internal bass bar and soundpost. The "Untreated" natural maple is preferred by many luthiers as it provides a consistent, organic material that is easy to carve and shape. With a 177mm height, there is plenty of room to adjust the string action for comfortable playability while maintaining excellent structural integrity.

Luthier Fitting Required

This is a raw bridge blank. For the best sound and to protect your instrument, the feet must be carved to match the arch of your bass top, and the top must be shaped to the correct height by a professional luthier.

Frequently Asked Questions

What is the "Etude" series?
The Etude series is Aubert's line of bridges designed for students and advancing players. They offer the same authentic French design and high-quality maple as their higher-tier models but are priced to be more accessible for educational and step-up instruments.

Does "Untreated" mean the wood is low quality?
Not at all. "Untreated" simply means the wood has not undergone a chemical seasoning process. Many professionals and luthiers prefer untreated bridges because they offer a very natural, organic sound and allow the wood to age naturally with the instrument.

Can I use this on a 3/4 size bass?
This bridge is sized specifically for a 1/2 size bass with a 136mm leg width. A 3/4 size bass generally requires a wider bridge (usually around 145mm-150mm) to ensure the feet are positioned correctly over the internal structure.
