Ibanez built the GSR100EXMOL as part of its SR (Soundgear) Series, positioning it as an entry-level four-string electric bass with a slim, player-focused profile. The GSR designation placed it within the more accessible tier of the SR family, intended to deliver the series' characteristic fast-neck feel at a lower build specification.
The bass was constructed with a poplar body finished in a mahogany oil treatment. The GSR4 maple neck carried a jatoba fretboard with white dot inlays and medium frets. Nut width measured 41mm, widening to 62mm at the 22nd fret, with neck thickness running 21mm at the first fret and 22mm at the twelfth — dimensions consistent with the SR line's emphasis on a slender, low-fatigue grip. The fretboard radius was 305mm. A 34-inch scale (864mm) drove the strings across a B10 bridge set at 19mm string spacing, with a passive PPD4 pickup at the bridge position. All hardware was finished in chrome.
Owners sourcing replacement parts — bridge saddles, tuning machines, or a compatible nut blank — should verify dimensions against the specifications above before ordering. A qualified guitar technician or luthier can assist with setup adjustments, fret work, or any wiring service the passive electronics may require.
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.
