All reeds are made to an initial aperture between 0.68-0.72 mm, but this will change slightly after the reed is played. The weld has been modified, resulting in significantly less air leakage without affecting the tone quality.
The total length of the reed is 69.8-70.2 mm and plays at 440-442 Hz depending on the positioning in the reed well. The O-ring diameter has been sized to fit most common oboe wells, however in uncommon instances they may be too large for older instruments. Our O-ring colours also dictate the strength of the reed: green for Medium-Soft, yellow for Medium and blue for Medium-Hard. A black O-ring is formerly Medium-Hard and no longer available. Medium-Hard reeds now have a blue O-ring.
While we are developing an American scrape reed in collaboration with some very prominent players in the US, American scrape players have found remarkable success using our Medium-Soft reed and adjusting their embouchure accordingly.
