Description

Ibanez built the SRMS805BTT as part of the SR Workshop Series, a sub-line positioned above the standard SR range and oriented toward players seeking extended-range instruments with premium tonewoods and multi-scale construction. The five-string bass featured a fanned-fret layout spanning a 34.0" short-side to 35.5″ long-side scale, a configuration intended to optimise string tension and intonation across the full range of a low-B tuning.

The neck was a five-piece Jatoba and Walnut laminate in the SRMS5 Multi Scale profile, joined to an Okoume body with a Poplar Burl top finished in Brown Topaz Burst. The bound Panga Panga fretboard carried 24 medium frets with acrylic special inlays, a 305mm radius, a 45mm nut width, and a 68mm width at the 24th fret. Neck thickness measured 19.5mm at the first fret and 23mm at the twelfth. Electronics consisted of a pair of passive Bartolini BH2 pickups—one at the neck, one at the bridge—routed through an Ibanez Custom Electronics 3-band EQ with an EQ bypass switch, a passive tone control on the treble pot, and a 3-way mid-frequency switch. The MR5S bridge offered 16.5mm string spacing. All hardware was finished in black. The instrument left the factory strung with D'Addario EXL170-5SL strings gauged .045/.065/.080/.100/.130 in standard B–E–A–D–G tuning.

Owners requiring replacement parts—such as a compatible MR5S bridge saddle, Bartolini BH2 pickup covers, or Panga Panga fretboard maintenance products—or needing setup work suited to a multi-scale instrument should consult a qualified luthier experienced with fanned-fret construction.

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.

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.
