The SRF ”Portamento” offers a Panga Panga fingerboard that extends the length of the standard SR neck to a hefty 30-fret length. Several years in the making, the SR Portamento's new AeroSilk piezo system delivers an uncanny touch of hollow-bodied openness, and realizes the innovative Upright Double Bass sound to blend into the mix that both inspires and redefines the role of the solid body bass.

For more than 40 years, Ibanez has pioneered new frontiers in bass development, pushing the boundaries of conventional designs to bass players of all styles, affording new avenues of expression and creativity. This spirit of exploration has led to the creation of some of the most successful and popular production basses of all time. Following this same drive to bring new and relevant ideas to the musical forefront is what serves as the basis for this ongoing project, dubbed the Ibanez Bass Workshop. The impetus behind each one of these unique instruments comes from a desire by the Ibanez bass development team to satisfy the particular needs of many players. These inventions may not be for everyone, but for those who yearn to explore new sonic vistas through the medium of bass: The Ibanez Bass Workshop project may give you just what you're looking for.
