The Reeds 'n Stuff pregouger is suitable for all instruments of the oboe family. Supplied with a pusher, the unique blade will allow the reed to be pregouged effectively.
 
We recommend choosing the diameter based on the cane diameter you are using.
 
For example, if you are using oboe cane with a diameter of 10.50 mm - 11.00 mm (10.50 mm - 10.75 mm), choose the pregouger with a diameter of 11.00 mm. 
 
If you are using oboe cane with a diameter of 10.00 mm - 10.50 mm, choose the pregouger with a diameter of 10.50 mm.
