Ibanez built the JS140MSDL as part of the JS Signature Series line, positioning it as an entry point into the JS family of electric guitars. The model carried the Soda Blue finish and was offered under the JS140M designation.
The guitar was constructed with a basswood body and a maple neck fitted with a maple fretboard bearing black dot inlays. Twenty-four medium frets ran across a 250mm radius board, with a nut width of 42mm and a 648mm (25.5") scale length. Neck dimensions measured 20mm at the first fret and 22.3mm at the twelfth, widening to 56mm at the twenty-fourth fret. The Edge-Zero II tremolo bridge, spaced at 10.8mm, handled pitch manipulation. Pickup duties fell to an Infinity RD humbucker at the neck — passive, ceramic — and a Quantum humbucker at the bridge — passive, alnico. All hardware was finished in chrome. The guitar left the factory strung with D'Addario EXL120s (.009/.011/.016/.024/.032/.042) in standard E tuning.
Owners sourcing replacement parts for the Edge-Zero II tremolo or the Infinity RD and Quantum pickups should verify compatibility by cross-referencing Ibanez parts documentation; a qualified guitar technician can assist with setup, intonation, and any tremolo maintenance specific to this bridge system.
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.
