Ibanez built the TMB30IV as part of the Talman Bass series, positioning it as a short-scale electric bass. The model carried an ivory finish, placing it within the TMB30 range as a colour variant distinguished by the "IV" suffix.
The TMB30IV was constructed with a poplar body and a maple neck bearing a jatoba fretboard with white dot inlays. Twenty medium frets sit across a 240mm radius board, with a nut width of 41mm widening to 62mm at the twentieth fret. Neck thickness measures 21.5mm at the first fret and 24.5mm at the twelfth. The 762mm (30") short scale is served by a B10 bridge with 19mm string spacing. Pickup configuration pairs a passive Dynamix P at the neck with a passive Dynamix J at the bridge — a split-coil and single-coil arrangement common to PJ-format basses. Hardware throughout is chrome. The instrument left the factory strung with .045/.065/.085/.105 gauges in standard EADG tuning.
Owners seeking replacement pickguards, PJ-format pickups, or B10 bridge components should verify measurements against their specific instrument before ordering, and consult a qualified guitar technician for any setup or wiring 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.
