Ibanez built the SR300ECUB as part of the SR (Soundgear) Series, positioning it as a mid-range four-string electric bass within a line long associated with slim, fast-playing profiles and active electronics integration. The model carried the Cerulean Aura Burst finish.
The bass was constructed with a Nyatoh body and a five-piece Maple/Walnut neck — a laminated construction Ibanez designated SR4 — joined to a Jatoba fretboard with white dot inlays and medium frets. The scale length ran 864mm (34"). Nut width measured 38mm, widening to 62mm at the 24th fret; neck thickness measured 19.5mm at the first fret and 21.5mm at the twelfth, with a 305mm radius. The Accu-cast B120 bridge provided 19mm string spacing. Pickups were a pair of passive PowerSpan Dual Coil units — one at the neck position, one at the bridge — feeding an Ibanez Custom Electronics 3-band EQ equipped with a 3-way Power Tap switch, which allowed tonal variation between pickup coil configurations. All hardware was finished in Cosmo black.
Owners sourcing replacement parts — including bridge saddles, pickup mounting hardware, or nut blanks — should bring the instrument's measured dimensions to a qualified guitar technician or luthier, who can confirm compatibility with current aftermarket components.
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.
