Jim Root Jazzmaster® Stark, dark and menacing, the crushing Jim Root Jazzmaster guitar has got to be the most distinctively minimalist version of the instrument ever devised in the model's entire half-century history. At the behest of the towering Slipknot guitarist, gone are the dual tone circuits and barrage of controls. Gone are the fret position markers and enormous chrome bridge. Gone, in fact, is pretty much everything typical of a Jazzmaster, replaced only by fearsome EMG® humbucking pickups with brushed nickel covers, single three-way switch and single volume knob, a hardtail bridge and little else.
