Many powerful sounding instruments are also a bit on the bright side. For those Arcus has developed its P-series bows. Their especially resilient stick allows to easily catch any heavy G-string and to play double stops in fortissimo without the stick touching down on the strings. Due to their elasticity and strength, they are also ideal for five-and multi-string violins. To make them draw a warmer, deeper sound, Arcus have added some weight which lowers the tuning of the bow. They are still significantly lighter than traditional bows, so they keep their advantage in agility and speed. The P-bows with octagonal sticks are especially lively and bounce almost automatically while the round version are especially steady and follow the hand precisely.
