Description

Ibanez built the SR400EQMSKG as part of the SR (Soundgear) Series, positioning it as a passive-pickup bass with active EQ — a configuration aimed at players who wanted tonal flexibility without the full commitment to active electronics. The quilted maple top over a nyatoh body gave the instrument its Surreal Black Burst Gloss visual identity, while the five-piece maple/walnut SR4 neck was characteristic of the broader SR line's emphasis on a fast, slim profile.

The neck runs a 34-inch scale with a jatoba fretboard fitted with white dot inlays and medium frets. Nut width measures 38mm, widening to 62mm at the 24th fret; first-fret thickness is 19.5mm, rising to 21.5mm at the 12th, and the fretboard carries a 305mm radius. Two PowerSpan Dual Coil pickups — passive units at both neck and bridge positions — feed into Ibanez's Custom Electronics 3-band EQ, augmented by a 3-way Power Tap switch that alters the coil configuration. The Accu-cast B300 bridge spaces strings at 19mm. All hardware is finished in cosmo black.

Owners sourcing a replacement bridge, nut, or tuning machines should confirm part dimensions against the specifications above before fitting; a qualified guitar technician or luthier can advise on compatible components and verify setup after any hardware swap.

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.
