Description

Ibanez built the B300 as an acoustic banjo in the natural finish, positioned as an entry point in the Ibanez banjo line. The instrument carries a 1/4" output jack, placing it in the electro-acoustic category and making it suitable for amplified performance as well as acoustic use.

The B300 features a mahogany back and sides with an okoume neck joined via screw jointing. The fretboard is purpleheart with a flat radius and special acrylic inlay, running 22 frets over a 670mm scale. The purpleheart and maple bridge pairs with a purpleheart saddle and a plastic nut measuring 32mm at the nut position. Neck dimensions are 21mm thickness at the first fret and 22mm at the seventh, with a body width of 14 inches and a maximum depth of 4 5/16 inches. Chrome friction tuners handle tuning, and the instrument ships from the factory set to 1D, 2B, 3G, 4D, 5G with a string gauge of .009/.016/.023/.030/.009 and a string spacing of 14.5. All exterior surfaces — top, back, sides, and neck — carry a gloss finish.

Owners researching head replacement, coordinator rod adjustment, or pot hardware compatibility should consult a qualified luthier or banjo technician familiar with the instrument's dimensions and construction.

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.

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.
