Ibanez announced the Roadcore RC320 guitar back in 2012 and it seems it must be popular as they have just announced two new Ibanez Roadcore models, the Prestige RC1320-DBS pictured above and the Premium RC720-CNF pictured below. There is one catch however, I saw these guitars on the Ibanez UK Facebook page and it seems they are showing on the EU Ibanez site, but not on the US site which is still only showing the Roadcore standard, as is the Australian site.
The Ibanez Prestige Roadcore RC1320-DBS features a Maple neck, Mahogany body, Rosewood fretboard w/Acrylic block inlay, an Ibanez Tight-Tune bridge, a Seymour Duncan® ’59 model humbucker in the neck position and a Seymour Duncan JB Model™ humbucker in the bridge position.
The Ibanez Premium Roadcore RC720-CNF features a 3pc Maple neck, a Rosewood top/back on Mahogany body, a Rosewood fretboard w/White dot inlay, Tight-Tune bridge, an Ibanez Core Tone (H) neck pickup and an Ibanez Core Tone (H) bridge pickup.
So if you are in the UK and you love the Roadcore, you are in luck. Everyone else you might have to import the premium or prestige versions.
