The RG670 is a Roadstar II series solid body electric guitar model introduced by Ibanez in 1989. The Roadstar II series would later become known as the RG series.
The RG670 features a basswood body bolted to a maple neck with a 24-fret rosewood fingerboard with dot position makers. Components include Ibanez pickups with a humbucker at the bridge and single-coils at the neck and middle positions, an Edge double locking tremolo bridge with a locking nut and Gotoh tuning machines.
It has a master volume which has a push/pull switch to split the coils on the bridge humbucker. Along with a tone knob it also has a mini-toggle which connects the bridge humbucker directly to the output jack — Ibanez billed this feature as the "kick off switching system".
The RG678 is a similar model with an ash body, sharktooth fretboard inlays and cosmo black hardware.
The RG670 was available only in Japan and was discontinued after 1989.
