Sliding into the Future of Fretless Bass
Over 25 years ago, the SR established Ibanez as the leader in innovative bass building. Throughout the yearsm we've made fretless versions of this classic for a limited number of the Ibanez artists. Now, the Ibanez Bass Workshop makes this much sought after option available to SR players everywhere with the introduction of the SR Portamento. The SR Portamento offers a Rosewood 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 Upright Double Bass sound to blend into the mix that box inspires and redefines the role of the solid body bass.
30 Fret Neck
The SR Portamento features an extended 30-fret Rosewood fretboard for playing in upper registers usually only accessible on an upright.
5pc SR Maple/Bubinga Thru-Neck
The SR Portamento features 5-piece Maple/ Bubinga thru-neck for increased sustain and superior tone.
Piezo Level Control
On the back of the SR Portamento are recessed controls assigned to each individual string to control the volume of the Ibanez-exclusive AeroSilk Piezo pickup. Perfect string balance and response can be achieved by adjusting the volume to accommodate different string gauges.
Custom bridge for AeroSilk Piezo System
The Custom bridge is created specifically for the optimum performance of the AeroSilk Piezo pickup system. Unique plastic saddles were designed to work in concert with the piezo pickups and enhance the acoustic "stand-up" quality of the sound.
Bartolini® MK-1 Pickups
The MK-1 pickups are a split coil design that provides a very wide frequency range and enhanced definition for maximum accuracy. The Neck and bridge pickups have equal response, like traditional single coils, but without the hum and noise.
AeroSilk Piezo system w/Active tone control
The EQ section incorporates the controls of the Bartolini pickups with the AeroSilk Piezo system. Controls include a Master volume, balance and bass & treble controls for the Bartolini MK-1 pickups and a Master volume and a tone control.
