The Guo end plugs have a unique feature that protects the octave key connecting lever. These are made to fit modern Selmer and Yamaha saxophones.
The Guo Musical Instruments Company had its humble beginnings in 1988. Although their initial handcrafted flutes offered only minor alterations to the original Boehm system, in 2003 the company introduced the Cermet Flute, thereby marking the beginning of what has become a devoted journey into the innovation of flute manufacture and design. This initial step, which remains a hallmark of all GMIC flutes to this day, was characterised by the exclusive use of computerised engineering for all aspects of an instrument construction and design. This allows for a level of consistency and reliability that had simply never been available by any other previous method.
