Over 25 years ago, the SR established Ibanez as the leader in innovative bass building. Throughout the years, Ibanez made fretless versions of this classic for a limited number of esteemed 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 innovative Upright Double Bass sound to blend into the mix that both 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 neck volume, bridge volume and bass & treble controls for the Bartolini MK-1 pickups and a Master volume and a tone control for the Piezo system.

    What a Nice Bass

    Comments about Ibanez SRF700 Portamento 4-String Fretless Electric Bass:

    I just bought this Ibanez SRF 700 Bass, I've never really used a Fretless outside of fooling around with one at the store a few times...but it did intrigue me and I wanted to get something different from my other Basses. Well, this is a VERY Nice Looking, Nice Playing and Sounding instrument for the money. It's very comfortable to play and I Love the Fretboard, it is Un-Lined (That was Important to me...seeing lines on the fretboard, to me, almost defeats the purpose of a Fretless Bass) Because, there are side markers and small Fret Lines on the side of the neck, I find it is extremely easy to intonate properly. So for me, I get the ease of playing on a very fast, comfortable neck, that I can feel as confident on as a normal Fretted Bass...but get that Fretless Sound and Feel...and the rather Cool Look of a Totally unlined 30 fret Neck. This is a Very Nice Instrument...if you like a 5 string, they have the SRF 705 model, and it's terrific, too.

    4.5 Stars - not your average Ibanez ... not your average bass

    Comments about Ibanez SRF700 Portamento 4-String Fretless Electric Bass:

    I bought this bass two weeks ago, and I really like it so far. The neck is awesome - low profile front to back, slim from E to G, with 30 + frets - well, no frets, which is the best part, of course. This bass has a smooth, slinky, deep, rich, low sound, due to the fretless neck and the third pick up at the (actual) bridge, which makes this bass sound hollow bodied, as the description above puts it, and low, low, low - but not too muddy, if you EQ the sound a bit. This really is a unique sounding bass, with a neck that's easy to play - that's what I like so much about it. It is light weight too, which I prefer (not a fan of Fender/Music Man, etc), yet the quality is great nonetheless - neck thru, and the hardware is nice and heavy duty. Cons: The tone is so low it's good to have a DI box with active EQ controls - this bass has plenty of its own EQ controls, but it really need a strong boost for the highs to ring out clearly. Also, the bridge was set way to low when I bought it, I had to adjust it a good bit to get rid of the buzz on the two high strings at the 1st - 4th frets. But overall, this is easily Ibanez's best, most innovative bass concept; even if you're not a fan of the company (and I definitely wasn't before I played this bass in GC), you still may dig it, so check it out.
