ESP Guitars has introduced the ESP Ninja and the LTD Ninja-600, 2 new Signature Series guitars created from a custom design by guitarist Michael Amott of Arch Enemy. The guitars join the group of 16 new Signature Series models being introduced by ESP at NAMM 2006.

The LTD Ninja-600 is designed in a unique and powerful V shape, with a Black finish and mirrored pickguard. The Ninja's Mahogany body is paired with a set-neck design at 24.75 in. scale. A 3-piece Mahogany neck with 22 extra jumbo frets on the Rosewood fingerboard also includes detailed custom X-shaped artistic inlays. Other features include chrome hardware, Tonepros bridge, Sperzel tuners, and Duncan JB/59 pickups.

"Michael Amott just plains rocks, and we are proud to add his Custom Shop ESP as part of the ESP and LTD Signature Series," says Allen Steelgrave, ESP Director of Marketing and Artist Relations. "Anyone who saw Arch Enemy on last summer's Ozzfest knows Michael's technique is as scary as anyone's. The ESP and LTD Ninja models are perfect for guitarists who want to add some aggression to their look and their sound."
