Ibanez built the JBM27 as part of its JBM Signature Series, positioning the model as a seven-string instrument within that line. It carried a Silver finish and was equipped for extended-range playing, shipped from the factory in Drop G# tuning.
The guitar was constructed with a Nyatoh body and a Maple top, paired with a three-piece Maple Wizard II-7 neck. The bound Jatoba fretboard featured jumbo frets and a JBM special inlay at the 12th fret. The 26.5" scale — 673.5mm — suited the low factory tuning, and the nut measured 48mm wide. Neck thickness measured 19mm at the first fret and 21mm at the twelfth, with a 400mm radius across the board. Electronics consisted of DiMarzio Titan humbuckers at both neck and bridge positions, passive and ceramic, with string spacing of 10.8mm at the bridge. Tremolo duties were handled by an Edge-Zero II-7 bridge, and all hardware was finished in black. The factory string set ran .011/.014/.018/.030/.042/.052/.064.
Owners sourcing replacement parts — including Edge-Zero II-7 components, DiMarzio Titan pickup covers or mounting hardware, or seven-string Jatoba fretboard nuts — should consult a qualified guitar technician to confirm dimensional compatibility before fitting.
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.
