Ibanez built the GSRM20PW as part of its miKro Series, a line of short-scale electric basses designed around a reduced overall length. The model sat at the entry level of the miKro range, offering a compact instrument for players requiring a shorter reach between positions.
The bass was constructed with a poplar body and a maple neck bearing the GSRM4 profile. The jatoba fretboard carried white dot inlays and medium frets, with a 305mm radius across its surface. The 726mm (28.6") scale length defines the instrument's character, and the neck measured 38mm at the nut, 58.5mm at the 22nd fret, 21mm thick at the first fret, and 22mm thick at the twelfth. Pickups consisted of a passive Dynamix P at the neck position and a passive Dynamix J at the bridge, mounted on a B10 bridge with 19mm string spacing. All hardware was finished in chrome.
Owners seeking setup adjustments, fret work, or compatible replacement parts for the B10 bridge, Dynamix pickups, or nut should consult a qualified guitar technician or luthier familiar with short-scale bass instruments.
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.
