The PGB1 is a four string solid body electric bass model introduced by Ibanez for 2007. It is a signature model for American bassist Paul Gray who was known primarily for his work with the American heavy metal band Slipknot. It was produced initially in South Korea; production moved to Indonesia for 2009.
The PGB1 features an ATK series double-cutaway swamp ash body bolted to a maple and walnut neck with a 22 fret rosewood fingerboard with special inlays at the second and twelfth frets. Components include a single Ibanez ATK triple-coil pickup, an ATK4 bridge, a plastic nut and Ibanez tuners with clover buttons.
For 2009, when production moved to Indonesia, several changes were introduced: the body material was changed to light ash, the finish was changed to burgundy wine and the neck was changed to laminated maple.
The PGB1L is a left-handed version (Gray was a left-handed player).
The PGB1 was discontinued shortly after Gray's untimely death in 2010.
