Harrison is a Chinese brand, and like many other Chinese brands, they are known for producing affordable replicas of popular instruments. Although Harrison saxophones are not identical to the originals, they come with many of the same features, such as intonation springs and adjustable keywork.
In general, Harrison saxophones are a good choice for beginners and casual players who are looking for a reliable instrument at a reasonable price. They are also well known for offering a variety of finishes, which makes them a great choice for players who are looking for something unique.
However, if you are looking for a professional saxophone, you should look at more expensive brands like Selmer, Yamaha, or Keilwerth. These brands are generally regarded as having better quality and sound.
