Description

Ibanez produced the GWB35BKF as part of the GWB Signature Series, a fretless electric bass line developed in collaboration with a signature artist. The instrument sat within Ibanez's dedicated signature bass programme, positioned for players seeking a fretless instrument with purpose-built tonal and ergonomic specifications.

The GWB35BKF was built on a basswood body with a three-piece maple neck and an ebony fretboard carrying off-set white dot inlay — a practical choice on a fretless instrument, where the dots serve as position markers rather than fret indicators. The neck measures 45mm at the nut and 68mm at the 24th position, with a thickness of 19mm at the first position and 21mm at the twelfth, over a 305mm radius. The 34-inch scale runs to 864mm. The five-string configuration is set up from the factory in standard B-to-G tuning and strung with D'Addario EXP165-5 strings gauged .045/.065/.085/.105/.135 at a 16.5mm string spacing. The passive SFR-GWB bridge pickup feeds the EQB-GWII two-band EQ. Hardware throughout is finished in black, matching the Black Flat body finish.

Owners sourcing replacement parts — including the SFR-GWB pickup, EQB-GWII preamp components, or the standard bridge — should verify compatibility against their specific instrument before fitting. A qualified luthier or bass technician can assist with setup, fretless fingerboard maintenance, and component matching.

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.

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.
