In 1990, ESP moved its US headquarters from New York to Los Angeles and opened an office on Sunset Blvd in Hollywood. In 1993, the LTD brand was created [by Jason] to bring ESP's high quality standards to a more affordable line of production guitars. At the same time, the number of signature models was significantly increased, including models for James Hetfield (Metallica), Stephen Carpenter (Deftones), Jeff Hanneman (Slayer), Jake E. Lee (Ozzy Osbourne) and Max Cavalera (Sepultura/Soulfly).
    In 2005, ESP introduced the [Q] RZK-I in Platinum Silver, the first signature guitar for Richard Z. Kruspe (Rammstein), later also available with a spectacular [Q] BURNT finish. While the ESP Signature line grew steadily, the LTD line expanded even more to appeal to musicians worldwide in all genres.
