Pearl Flute Pinless Construction
The foundation of every Pearl flute is a patented Pinless construction, which eliminates the problems of traditional flute construction - protruding needles that snag clothing and give easy entry to perspiration and body acids causing corrosion and binding keys. Besides this unique pinless construction, Pearl flutes have additional bridge mechanisms that add strength to the entire mechanism. Plus, socket-head screws are inserted from the underside of the key work, preventing the entry of perspiration into the mechanism.
Pearl Flute One-Piece Core-Bar Construction
The One-Piece Core-Bar construction of all Pearl Flutes eliminates many of the wear and tear problems associated with traditionally constructed flutes, specifically in the areas of the high C key and the king post next to the F# key. Pearl has designed one rod that extends from high C through the king post resulting in an extremely reliable mechanism that plays more comfortably, stays in adjustment longer and is easier to service.
