Many names for the same thing - the little tube onto which the cane is tied
The Nissen Tube is - to say it shortly - a standard oboe tube, where the cork is removed from the tube, and a plastic part is mounted instead. Rubber rings makes the tube sit firmly in the oboe. The metal tube is unchanged, the plastic part is designed to fit standard brass or nickel silver tubes from makers like Glotin, Pisoni, Lorée, Rieger, Rigotti, Windfield etc. The only new thing is the plastic part. You do not have to change your reed style or technique. The surprising result of this simple procedure is incresed Focus, Clarity and Stability.
