Ibanez built the GSR205BWNF as part of the SR Series bass line, positioning it as a five-string passive instrument within the GSR sub-range. The GSR designation placed it among the more accessible tiers of the SR family, while retaining the core construction principles associated with that series.
The bass is built on a Nyatoh body finished in Walnut Flat. The GSR5 maple neck carries a Jatoba fretboard with white dot inlays and medium frets, with a nut width of 45mm, a width of 67mm at the 22nd fret, and a 305mm radius. Neck thickness measures 21mm at the first fret and 22mm at the twelfth. The 34-inch scale (864mm) is paired with a B15 bridge set at 16.5mm string spacing. Pickup duties are handled by a passive Dynamix H humbucker at the neck and a passive Dynamix H humbucker at the bridge, with the Phat II EQ providing onboard tone shaping. All hardware is finished in black.
Owners requiring setup work, fretboard maintenance, or compatible replacement hardware — including bridge saddles sized to the 16.5mm string spacing or components matching the B15 bridge — should consult a qualified guitar technician or luthier familiar with five-string 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.
