The RGD series is a line of electric guitars produced by Hoshino Gakki and sold under the Ibanez brand. The series was introduced in 2010. The RGD models feature a new body style. The new style is based on the traditional Ibanez RG, but has a beveled body cut and extra deep horn cut. RGD models also feature an extra long 26.5" (672mm) scale neck. With the long scale, the RGD models generally appeal to players who want to tune their guitar down, particularly those who play mostly metal.
