Double bass extensions have evolved quite a bit over the years.
Introduced in the early 1900s as a way for basses to reach a low C, earlier generations of extensions used machines to control levers and play low notes. These machines were often noisy contraptions that were prone to buzzing and other kinds of mechanical failure.
In the early 1990s, a new type of extension featuring a set of individually adjustable keys emerged. These state-of-the-art extensions allowed for low notes to be opened or closed in multiple configurations. This new style of extension has continued to grow in popularity and is now the dominant form of C extension on the double bass market.
The Eastman Bass C Extension has been designed in close collaboration with Lisa Gass of L.A. Bass Works. The state-of-the-art device allows for low notes to be opened or closed in multiple configurations. Additionally, the extension is fully adjustable, allowing the player to dial in the exact pitch for each low note.
