PRODUCT DESCRIPTION
- High-End Design All instruments in the Bach Stradivarius series are handmade in America ensuring the highest standard of engineering. The highly skilled craftspeople are still using the original designs used from the 1920s. The open wrap F attachment found on the Bach 42BO makes a single large loop to help reduce both air resistance and the number of connections between the main body and F attachment. This offers less back pressure and a more open feel when the trigger is engaged. Because of this the open wrap system is the favourite for many musicians who prefer freer playing and less vibration. The Bach 42BO features a .547" large bore which is typical of most premium symphonic trombones. This is because it produces a large and rich sound which is ideal for orchestral or solo performances. The 8-1/2" one-piece hand-hammered yellow brass bell on the 42BO has defined the orchestral trombone sound for generations and will project the sound to the back of any sized concert hall. Premium Brass Bach only uses the highest quality materials to construct their Stradivarius trombones. The yellow brass found in the bell and outer slide provides a nice balance between the various playing parameters which makes it the most widely used and commonly played alloy in the world. The 42BO has a chrome plated nickel silver inner slide which provides a bright and powerful sound to the performer. Nickel silver is used for many premium trombone slides because its firmer and has greater corrosion resistance compared to standard brass. Once the 42BO has been constructed a layer of clear lacquer is applied to make sure the instrument stays looking newer for longer. The Stradivarius Series The Stradivarius series of instruments are the premium symphonic models originally designed and manufactured by Vincent Bach in the early 1920s. All of the models in the Stradivarius range are made using the highest quality materials to ensure only the best possible instruments are produced. The name "Stradivarius" originates from the first trumpets made by Vincent Bach himself. Musicians would refer to his original trumpets as having a "Stradivarius" sound which later inspired the name Stradivarius. About Bach Bach have been making trumpets since 1924 and are viewed as one of the best trumpet manufacturers in the world. Musicians frequently referred to Bach trumpets as having a real "Stradivarius" sound referring to the world-famous string instruments. In 1928 Bach decided to use their expertise to start manufacturing trombones and have since grown to gain a reputation similar to their trumpets.
