Ibanez built the SR375EFBBT as part of its SR (Soundgear) Series, positioning it as a fretless five-string electric bass within a line long associated with slim, fast-playing necks and active electronics geared toward players seeking a more articulate, low-profile instrument.
The bass was constructed with a maple body and a five-piece maple/walnut SR5 neck, the latter a construction method Ibanez used to add rigidity and resist seasonal movement. The jatoba fretboard is unlined fretless, carrying white dot position markers, with a 305mm radius and a nut width of 45mm tapering to 68mm at the twenty-fourth position. Neck thickness measured 19.5mm at the first position and 21.5mm at the twelfth. The 34-inch scale — 864mm — ran through an Accu-cast B125 bridge with 16.5mm string spacing, finished in cosmo black hardware throughout. Two passive PowerSpan Dual Coil pickups, one at the neck and one at the bridge, fed into Ibanez's own Custom Electronics 3-band EQ equipped with a 3-way Power Tap switch, giving the player passive coil-configuration options alongside active tonal shaping.
Owners setting up or servicing this instrument — particularly for fretless intonation, nut work, or pickup height — should consult a qualified guitar technician familiar with fretless bass setup, as the lack of frets places additional precision demands on action and relief adjustments.
STRAIGHT TALK
What Stands Out
Keep In Mind
From the people who own them
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.
Owner photos
Put yours on the record.
The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.
What do you know about this one?
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.
