The Ibanez JSM10 VYS John Scofield Signature Guitar. Part of the Ibanez Signature Series and JSM Neck Type. This JSM10 of Scofield's Signature instrument reflects his desire to offer a Guitar that meets his high standards, but falls within the reach of young working players. The JSM10's semi-hollow Flamed Maple Body is visually refined work of craftsmanship that enables clean, clear, warm tone: a character further enhanced by the solid Sapele neck.
