    Trombone Outfit w/Infinity Axial Flow Valve - silver plated

    The Bach Stradivarius 42AF is a professional large bore (0.547") symphonic trombone with a new generation "Infinity" Thayer valve and open wrap F attachment. The Infinity valve provides for an uninterrupted airflow through the valve section. This makes the horn especially free-blowing, allows the F attachment notes to match the open horn in both tone and feel, and makes for a fuller low register.

    New for 2011, the 42AF is the replacement for the venerable 42T and features three major improvements over the earlier model.

    • First is the valve. The "Infinity" thayer axial flow (AF) valve on this model is unique in that it employs an upper and lower roller bearing assembly to support the valve core. These bearings are similar to those used in precision machine andautomotive applications. They support and align the valve core which eliminates surface wear and allows for an air-tight seal, two issues that have been problematic in the axial flow valve design since it first appeared in the 1980's. This lightning fastvalve is complimented with a new miniball valve linkage which makes for a design that's comfortable, fast, tight and responsive.
    • Second is the handslide. Bach has adopted a new state of the art slide manufacturing process that employs a pre-polishing stage. The result is a slide that is truely world class. Gone are the days of hiss and scratch. The new slides are fast,even and nearly silent. And as a bonus, the slide lock has been improved for worry free operation.
    • Third is a new fixture-mounted construction process. This results not only in improved alignment of parts, but also better resonance and thus improved sound.
    General 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.
    • Silver plated 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. Silver plating further makes the instrument have a more brilliant/bright tone and as such is rarely employed in classical music situations due to its effect on tone.
    • Infinity Axial Flow Valve. The Bach Infinity valve provides for an uninterrupted airflow through or past the F attachment. Conical shaped, and rotating about its axis on precision roller bearings, the valve provides a straight-through air path with no resistance whatsoever. Axial Flow valves make the horn especially open and free-blowing, allow the F attachment notes to match the open horn in both tone and feel, and makes for a fuller low register.
    • 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.
    • Nickel silver slide handgrips. Lacquered nickel grips resist corrosion far better than brass grips and also prevent staining of your skin.
    • 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.
