Woodwind accessory maker Key Leaves has released its new Oboe Key Props , which cure sticky key pads that cause play malfunction .
The new Key Leaves oboe care product adapts to serve any model oboe and features soft rubber props that safely open C , B , plus two high trill keys so the pads air dry .

Avantone Pro has introduced the CLA- 400 , a classically-designed Class A / B amplifier designed to be paired with large passive monitors . It ’ s the bigger brother to the CLA-200 studio reference amplifier .
The CLA-400 can generate over 400W per channel into an 8Ω load , lending its use as a good fit for medium to large passive monitors in a studio environment with its standard 3U rack-mount chassis . The CLA-400 is a dynamic , high-output , high-resolution , full-range system built the old-school way — as a classically-designed Class A / B amplifier . As such , Avantone Pro says it paid particular attention to creating an amplifier in the traditional studio style , with ample analog VU ( Volume Unit ) meters , high-quality Japanese components , and a toroidal transformer linear power supply , as well as implementing a classic bipolar transistor design delivering a robust bottom end . The CLA-400 ’ s convectioncooled design makes for silent operation . This means it can reside in the same location as the passive monitors to which it is providing power .
