Description

Ibanez built the S521BBS as part of the S Series line, a range designed around the thinly contoured, lightweight body format that defined the S family's place in the Ibanez catalogue. The S521 sat in the mid-tier of the series, offering the core S Series construction and hardware package at an accessible point in the line.

The guitar was constructed with a Meranti body and a Wizard III Maple neck, a profile Ibanez developed for fast, low-fatigue playing. The Jatoba fretboard carries 24 jumbo frets with off-set white dot inlays, a 400mm radius, and a nut width of 43mm. Neck thickness measures 19mm at the first fret and 21mm at the twelfth. The 648mm (25.5") scale length feeds into an F106 bridge with 10.5mm string spacing. Electronics consist of a pair of passive, ceramic-magnet Quantum humbuckers — one at the neck, one at the bridge — with all hardware finished in cosmo black. The guitar left the factory strung with D'Addario EXL110s (.010–.046) in standard E tuning.

Owners sourcing replacement parts should note that the F106 bridge and its 10.5mm string spacing, the Wizard III neck dimensions, and the 400mmR fretboard radius are the key figures for finding compatible saddles, nuts, or fretboard work; a qualified luthier or guitar technician familiar with Ibanez S Series hardware will be best placed to advise on direct replacements and setup tolerances.

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.

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.
