built in F extension
This is a Hoyer Bb single with 5 valves.
The 2 extras allow for handstopping without transposing (or playing in E without transposing – though the Establishment may not approve of this) and F basso open harmonics.
It is a lightweight instrument more suited to a high player than a low register specialist but will supply plenty of fun. Perfect for quintet work.
Yellow brass, fixed bell, unlacquered, serviced and in good order ready to be played.
