Ibanez positioned the B50 as an entry-level acoustic banjo in its acoustic instrument line. The instrument is a five-string banjo finished in Natural gloss across the body, neck back, and top.
The neck is Okoume, joined to the body via screw jointing, and carries a Purpleheart fretboard with white dot inlays across 22 frets. The fretboard radius is flat, consistent with traditional banjo construction. The nut is plastic, set at 32mm width, and the string spacing at the bridge is 14.5mm. The Purpleheart bridge and saddle carry the factory tuning of 1D, 2B, 3G, 4D, 5G across a string gauge of .009/.016/.023/.030/.009. The scale length is 670mm. Tuning is handled by chrome open-gear tuners. Body back and sides are Mahogany, finished in gloss.
Owners sourcing replacement parts — bridge, tuners, nut, or strings — should verify measurements against the dimensions recorded here before purchasing, and consult a qualified instrument technician for setup adjustments or structural work.
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.
