The Bach 42AF Stradivarius Series Axial Flow F Attachment Trombone features superior engineering, precision fabrication and unmatched performance in a professional level instrument. The 42AF series features a new patented axial flow valve with sealed ceramic top and bottom bearings that allow for smooth balanced action with low maintenance, no surface wear and superior compression. The mini-ball valve linkage allows a free, responsive movement, while the granadilla wood thumb lever offers an elegant look and comfortable feel.
This trombone also features a new single draw hand slide fabrication process for a more consistent slide surface that allows a quiet performance and a smooth feel. The fixture mounted construction process allows for proper alignment and freer vibration throughout the instrument.
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. New for 2011, the 42AF is the replacement for the venerable 42T.
