Pro Vibe Series The Mike Balter Pro Vibe Series carries on a heritage of performance and reliability with a distinctive style. The heavier, round shaped cord wound mallet head provides the preferred vibe sound. Ready to impress in any situation, the Pro Vibe Series with its ideal weight and balance is the all-around choice for today’s player. Available in Satin Birch, Black Birch, Two-Stage Fiberglass, or Rattan Handles. Birch Handles, are a light weight, extremely strong, durable material that supplies a firmer feel. Because of the diminished flexibility especially on long length models. Birch Handles have become the standard choice for today’s marimba artists. Rattan Handles provide excellent rebound with an optimum amount of flexibility when striking the instrument. It is the vibe player’s choice because of its “give” which is especially useful in mallet damping. Rattan is also an ideal handle for bell and xylophone mallets and is the professional’s choice. When ordering keyboard mallets indicate handle choice by adding the following suffix to each model number: B for Satin Birch, BB for Black Birch, F for Two-Stage Fiberglass, R for Rattan.
