Ibanez built the GWB205TQF as part of the GWB Signature Series, a line of fretless electric basses developed in association with the series' namesake artist. The five-string configuration and dedicated pickup and preamp selection placed it toward the more specified end of that series, targeting players who required extended low-end range alongside the tonal flexibility of a fretless instrument.
The GWB205TQF was constructed on an ash body paired with a three-piece maple neck designated the GWB profile. The ebony fretboard carried off-set white dot inlays and was finished without frets, with a 305mm radius and a nut width of 45mm widening to 68mm at the 24th position. Neck thickness measured 19mm at the first position and 21mm at the twelfth. String spacing at the bridge was 16.5mm across a standard bridge finished in black hardware. Electronics comprised a passive Bartolini GWB bridge pickup feeding a Bartolini NTBT 2-band EQ. The instrument left the factory strung with D'Addario EXP165-5 strings gauged .045/.065/.085/.105/.135 in standard five-string tuning B–E–A–D–G, across a 34-inch scale.
Owners seeking setup assistance, fretless fingerboard maintenance, or compatible replacement parts — including Bartolini-format pickups and preamp components — should consult a qualified luthier or experienced bass technician familiar with fretless 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.
