How long should it take to get adjusted to a new mouthpiece?
The answer to this question is different for everyone. There are no right or wrong answers here. Some people take longer to adjust to new mouthpieces than others. Ideally, a new mouthpiece should be better from the very beginning. Perhaps a new batch of reeds is the only thing necessary for the proper adjustment to take place. From that point on, it is entirely up to the individual.
