Ibanez built the SR370ESPB as part of the SR (Soundgear) Series, positioning it as a mid-tier four-string electric bass within a line long associated with slim, fast-playing necks and active electronics.
The bass was constructed with a maple body and a five-piece maple and walnut SR4 neck, a laminated configuration Ibanez used across the SR range to add stiffness and stability. The jatoba fretboard carries white dot inlays and medium frets, with a 305mm radius and a 34-inch scale length. Nut width measures 38mm, tapering to 62mm at the 24th fret, with neck thickness running 19.5mm at the first fret and 21.5mm at the twelfth. String spacing at the Accu-cast B120 bridge is 19mm. Passive PowerSpan Dual Coil pickups sit at both neck and bridge positions, feeding into Ibanez's own Custom Electronics 3-band EQ equipped with a 3-way Power Tap switch — a configuration that allowed blending between coil modes without active pickup circuitry. All hardware was finished in cosmo black.
Owners seeking replacement parts — including bridge saddles compatible with the Accu-cast B120 footprint, PowerSpan-format pickup covers, or setup guidance for the jatoba fretboard — should consult a qualified guitar technician or luthier with experience in production bass instruments.
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.
