Arcus M6 Cello Bow
The somewhat heavier and softer sticks lower the tuning of the M-bows and allow them to draw a particularly warm, round sound from smaller celli that typically sound quite bright (e.g. Stradivari or Ruggeri models). Though the sound may appear softer, power and projection are significantly enhanced.
With an M6 in your hand, it would be quite a challenge to find a wooden bow, no matter its price, that matches its sound in depth, richness, projection, power, or clarity, not even matching its superior agility, comfort, power, and durability. Its warm sound makes the M6 especially suitable for brighter-sounding instruments.
