The Wilkinson®-Gotoh® VSVG tremolo unit features smooth arm action and the unique design of its elongated baseplate screw holes help promote accurate pitch return by eliminating binding. Its locking bent-steel saddles provide a vintage tone and feel. A smooth taper volume filter maintains the guitar’s high frequencies at low volumes and provides more uniform tone from 1 to 10. The combination of DiMarzio® The Cruiser® pickups deliver single-coil tone, open vocal-sounding mids and a bit of added strength to the bass. These pickups also relieve players of string drop-outs and sustain-killing magnet pull. The Oil-impregnated bone nut provides superior tuning stability and warm rich resonance. Stainless steel frets boast excellent corrosion resistance. The wide and tall fret-type offers a quick response, good articulation when playing chords and clear tone when playing single notes. S-TECH special roasted treatment provides a superior attack and a well-balanced tone and a rich sustain. In order to achieve supreme neck grip comfort, the fretboard edge is finished with a smooth curve. The AZ comes with GOTOH® MAGNUM LOCK® machine heads, which have an established reputation for tuning stability. Its H. A. P® (Height Adjustable Post). system allows for the adjustment of string posts for the appropriate tension of each string.
