The XS20 is the most affordable set of B20 brass cymbals in Sabian's range. B20 is considered to have the widest frequency range, therefore cymbal manucaturers can manipulate the material into many different sound specifications. The XS20's have been designed to represent the crisp, biting sound of vintage bright cymbals. This series is ideal for a drummer looking to upgrade a beginners set to a more intermediate level. They are also widely recommended as a sensible first buy, as they will last far longer than any normal beginner set due to the higher quality brass components they are made of.
