Description

Ibanez built the GSRM20TR as part of the miKro Series, a short-scale electric bass line positioned for players requiring a reduced-length instrument. The GSRM20TR sat within that series finished in Transparent Red.

The bass was constructed with a poplar body and a maple neck designated GSRM4, carrying a jatoba fretboard with white dot inlays and medium frets. The nut measured 38mm wide, widening to 58.5mm at the 22nd fret, with neck thickness running 21mm at the first fret and 22mm at the 12th. The fretboard radius was 305mm. A 726mm (28.6-inch) scale length defined the instrument's short-scale character. Pickup configuration followed a split-coil Dynamix P at the neck and a single-coil Dynamix J at the bridge, both passive. The B10 bridge offered 19mm string spacing. All hardware was finished in chrome.

Owners sourcing replacement parts — bridge saddles, nut blanks, pickups or tuning machines — should verify compatibility against the specific component dimensions listed above, and consult a qualified guitar technician or luthier for setup and installation work.

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.
