A lot of people ask about the difference between filed and unfiled reeds. Here's a brief explanation:
An option to fine-tune the sound, the file is often preferred by players who use traditional, moderately resistant, dark-sounding mouthpieces– the file helps such mouthpieces blow more freely.
For those who play relatively easy-blowing, moderate-to-bright mouthpieces (especially jazz or pop sax mouthpieces with a high baffle), an unfiled reed is usually preferred.
The French File (or “file”) is the area behind the vamp (or cut portion) where the bark is sanded
off in a straight line.
The File-
Provides ease of response, especially in the low register… …making soft attacks easier.
Also makes the tone slightly brighter… …for use with resistant mouthpieces.
An unfiled reed provides a darker tone and more resistance; a filed reed provides a brighter tone and is more free-blowing.
