Re: Vandoren Java reed id help please
You just need to know how to identify a filed reed.
Hold both reeds vertically, facing to you.
On the filed reed, there is a perfectly horizontal line (perpendicular to the grain of the reed), that separates the base of the reed from the tapered/shaved part.
On the unfiled reed the taper blends into the rounded base forming the shape of a U.
The filed is the red evidently.
In the future, try a using a sharpie when you open the reed up for the first time.
