The demand for power by modern orchestras prompted the introduction in 1991 of the Model 601D bassoon, which featured thicker walls than earlier designs. This results in longer, larger, more resonant tone holes, and a tone quality that is bigger, yet slightly less concentrated than the short or long bore models. The Model 601D is the longer version and is slightly flatter with a warmer tone quality. It is somewhat more work to play, but it delivers more power when pushed, yet can easily handle soft attacks. It was designed and developed under the supervision of Alan Fox in conjunction with prominent bassoonists in major symphony orchestras. Like all Fox bassoons, it features freedom of response, intonation, tonal quality, and projection that will satisfy the requirements of the most discriminating performers.
