The Bach Stradivarius 42BO is a professional large bore (0.547") symphonic trombone with a yellow brass bell, brass slide and an open wrap F attachment. The Bach 42 series trombone has defined the modern symphonic trombone sound. It has been copied in whole or part by many other makers, from large manufacturers to small specialty makers. The 42's characteristic sound is dark and resonant, with little edge and great carrying power. Like many of Vincent Bach's designs, it is famous for its ability to "slot," and for its uniformity of tone throughout its scale and dynamic range. It is especially well suited for orchestral work, where it can disappear into, subtly blend with or completely dominate an ensemble. Features include:
8.5" one-piece hand-hammered bell. A one-piece bell generally gives a better response over two-piece designs due to the lack of the additional solder joint at the bell flare.
Yellow brass bell material. Though subject to debate, yellow brass is often thought to make for better projection with more clarity than red, rose or gold brass.
Brass outer slide tubes. Brass outer tubes are generally thought to help produce a darker, more intense sound with great projection that is less apt to "break up" at high volume levels.
Seamless chrome-plated nickel silver inner slide tubes. The lack of a seam helps make the inner tubes perfectly round—they don't flatten or bulge at the seam. This, together with the polished nickel finish makes the action quick, light and quiet.
Rotary Valve. The standard rotary valve is a reliable and airtight device used to shunt airflow into or past the F attachment. Rotor valves are easy to maintain and unless bone dry, will not leak. While rotor valves provide more resistance than advanced freeflow designs, many players actually prefer this feedback.
Open Wrap F Attachment. An open wrap F attachment provides for a slightly improved airflow through the valve section over a traditionally wrapped model. This allows notes played on the valve to speak more easily and to sound more natural.
Nickel silver slide handgrips. Lacquered nickel grips resist corrosion far better than brass grips and also prevent staining of your skin. They are harder than brass and help lower the overall weight of the horn.
Tubular nickel silver body braces. Nickel braces are lightweight and tough, reducing weight and increasing body integrity.
Bach 6.5A mouthpiece. The 6.5A is a decent mouthpiece for this horn. It can be swapped for a 5G (a better match for experienced players) or any other in-stock Bach mouthpiece of similar cost at no additional charge.
Wood shell case. Bach's case is protective and durable. New shaped design is slimmer than previous models and features latches instead of zippers.
Metal cleaning rod. Standard with every Bach Strad trombone. You're going to need one anyway, and this saves you the expense later on.
