Vienna Symphonic Library - Bass Trombone [Kontakt]

The bass trombone is a slide trombone with two valves that are operated by the left thumb. The valves make it possible to lower the instrument’s pitch from Bb to F or D. The entire chromatic scale only becomes available thanks to the thumb valve (F tuning) and an additional third-valve (D tuning). The bass trombone has a very wide range and is relatively easy to play in the lower register.
