Description

Ibanez built the SRF706BBF as part of the SR Workshop Series, positioning it as a fretless six-string bass within a line defined by premium tonewoods and extended-range versatility. The neck-through construction and fretless fingerboard mark it as a specialist instrument aimed at players seeking a more expressive, legato approach to low-end performance.

The SRF706BBF is built around a five-piece Maple and Walnut neck-through design with Okoume wing body halves and a bound Panga Panga fretboard. Hardware is finished in Cosmo black throughout. The electronics pair passive Bartolini MK-1 pickups at neck and bridge positions with an Ibanez 2-band EQ that incorporates a Piezo active tone control fed by a Custom AeroSilk Piezo system bridge — an arrangement that blends magnetic and piezo sources. The instrument ships with D'Addario ECB81 Flatwound strings gauged .045/.065/.080/.100 and is factory-tuned B–E–A–D–G–C. String spacing at the bridge sits at 16.5mm. The neck measures 54mm across at the nut and 83mm at the 24th fret position, with a thickness of 21.5mm at the first fret rising to 23.5mm at the twelfth. Fingerboard radius is 400mmR and scale length is 864mm (34 inches).

Owners requiring fretless setup work, piezo system adjustment, or string replacement guidance should consult a qualified guitar technician or luthier familiar with extended-range fretless instruments.

Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.

Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
