The G bass trombone lacks the lowest notes available to the earlier F bass trombones. Adding a thumb valve not only extends the range but also increases agility by reducing slide movement. This was the first G+D trombone made by Boosey & Hawkes. These instruments were called Betty Model in the company's books after noted orchestral trombonist William Betty. G+D trombones were produced until the 1970s, but in the later years of production were only played in brass bands before they, like orchestras, changed to the wide bore B flat+F bass trombone.
