Euphonycart Present Ibanez RGDIX7MPB SBB Iron Label. The Ibanez RGDIX7MPB SBB Iron Label 7-string electric guitar’s poplar burl-topped ash body creates the perfect blend of brightness, resonance, and sustain. A pair of coil tapped DiMarzio Fusion Edge 7 humbuckers yields an amazing clarity and smooth response that lends well to progressive metal. We love these pickups here at Sweetwater. They sound great whether you’re playing crystal clear or in high-gain heaven. Complete with a comfortable 3-piece maple/bubinga Nitro Wizard-7 neck and fast-playing bird’s-eye maple fingerboard, prog metal guitarists are raving about the Ibanez RGDIX7MPBSBB RGD Iron Label 7-string electric guitar!
