Ibanez built the GSR205BK as a five-string entry in their SR Series electric bass line. The GSR sub-series positioned the instrument toward players seeking a full-range, multi-string platform at an accessible tier within the broader SR family.
The GSR205BK is built on a poplar body paired with a maple neck designated GSR5. The fretboard is jatoba with white dot inlays and medium frets, running a 34-inch (864mm) scale. Nut width measures 45mm, widening to 67mm at the 22nd fret; neck thickness runs 21mm at the first fret and 22mm at the twelfth, with a 305mm radius. String spacing at the bridge is 16.5mm. Pickups are a passive Dynamix H at the neck and a passive Dynamix H at the bridge, fed through the Phat II EQ circuit. Hardware is finished in chrome, and the bridge is the B15 unit.
Owners sourcing replacement parts — including B15 bridge saddles, Dynamix H pickup covers, or jatoba fretboard care products — or requiring a setup adjusted for the 16.5mm string spacing should consult a qualified guitar technician or luthier familiar with multi-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.
