The RG140 is one of only a few RG models produced with a 22-fret neck. It is also among a small number of RG guitars with a humbucker/ single/ single pickup configuration. It has the rounded-edged body style which distinguishes it from the more sharp-edged modern RG body. The RG140 features a basswood body bolted to a maple neck with a 22-fret rosewood fingerboard with dot position markers. Components include pickguard-mounted Ibanez pickups with a humbucker at the bridge and single-coils at the neck and middle positions and a Powerocker tremolo bridge.
