This reed model in regular playing strength is intended for advanced and regularly practising players.
It has a slightly higher blowing resistance than the light version, offers a somewhat fuller tone, responds well, and is easy to play freely across all registers.
The reeds should be played in over a period of about 4–6 days. During this time, they may change a bit and may need some adjustments.
