Jim Root Jazzmaster® V4 For heavy, molten metal riffage, the Jim Root Jazzmaster® V4 delivers crushing detuned tone with a bold new look. We worked closely with the towering Slipknot guitarist to create a brutal-sounding signature Jazzmaster model that complements his heavy playing style—right down to its signature Daemonum™ open-coil EMG® active pickups, shred-worthy 12” radius fingerboard with jumbo frets, sparse control layout and more. The Jim Root Jazzmaster II dispenses with frivolities such as a vibrato, rhythm circuit, tone control – only crucial essentials remain: a volume control, a 3-way switch and a hardtail bridge, making this guitar a single-purpose weapon of mass destruction. Featuring a mahogany slab body for crushing lows and mids, brilliant Polar White satin finish, maple neck with bound ebony fingerboard and pearloid block inlays, this devastating machine delivers brutal tone with a striking new look.
