Ibanez built the BTB1826NTL as part of the BTB Premium Series, positioning it as a high-specification six-string electric bass with a neck-through construction. The model carried the Natural Low Gloss finish and sat toward the upper tier of the Premium range, distinguished by its multi-laminate through-neck design and boutique pickup complement.
The neck ran seven pieces of Panga Panga, Purpleheart, and Maple with graphite reinforcement rods — a construction intended to resist seasonal movement across a long scale of 889mm. The Ash wing body carried a Walnut top and Walnut back, and the bound Panga Panga fretboard featured abalone off-set dot inlays over 24 frets plus a zero fret, finished with medium Stainless Steel frets and a premium fret edge treatment. String spacing at the MR5S bridge measured 17mm. Electronics consisted of a passive Aguilar DCB neck pickup and a passive Aguilar DCB bridge pickup, fed into an Ibanez Custom Electronics 3-band EQ with an EQ bypass switch — passive tone control on the treble pot — and a 3-way mid-frequency switch. Hardware throughout was gold. The nut measured 54mm wide; the fretboard reached 85mm at the 24th fret, with neck thicknesses of 20mm at the first fret and 22mm at the twelfth, over a 950mmR radius. The instrument left the factory tuned 1C/2G/3D/4A/5E/6B and strung with D'Addario NYXL32130SL strings gauged .032/.045/.065/.080/.100/.130.
Owners seeking replacement parts — including MR5S bridge components, Aguilar DCB pickups, or fret wire matched to the original medium Stainless Steel specification — should consult a qualified luthier or guitar technician familiar with extended-range 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.
