Ibanez built the BTB745NTL as part of the BTB Series, a line positioned around extended-range, long-scale electric basses designed for players who required a wider string spacing and deeper tonal foundation than Ibanez's more compact bass formats provided. The BTB745NTL was a five-string model finished in Natural Low Gloss.
The bass was constructed with a neck-through design using a five-piece Maple and Walnut neck reinforced with graphite rods, mated to an Ash/Okoume wing body with a Walnut top. The 24-fret (plus zero fret) Jatoba fretboard carries Abalone dot inlays, medium Stainless Steel frets, and a 400mm radius. The neck measures 47mm at the nut and 76mm at the 24th fret, with thickness running 20mm at the first fret and 22mm at the twelfth. Scale length is 889mm (35 inches). Passive Bartolini BH2 pickups sit at neck and bridge positions, fed through an Ibanez Custom Electronics 3-band EQ. The MR5 bridge offers 19mm string spacing, and all hardware is finished in Cosmo black. The instrument left the factory strung with D'Addario NYXL45130 strings (.045/.065/.080/.100/.130) in standard five-string tuning B–E–A–D–G.
Owners sourcing replacement parts — including Bartolini-compatible pickups, MR5 bridge components, or Jatoba fretboard materials — should consult a qualified luthier or bass technician for fitting advice, particularly given the neck-through construction and 35-inch scale considerations.
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.
