You can bet the music is turned all the way up at Line 6, a leading maker of electric guitar amplifiers. Line 6 focuses on integrating technology with music products, such as its digital modeling amps that are designed to reproduce the distinctive sounds of a wide range of traditional tube amps and much more. Beyond a wide array of amps, the company makes and sells Variax guitars, stomp boxes, pedals, and other accessories. Line 6 amps are sold in more than 60 countries through major music retailers such as Guitar Center and Sam Ash as well as on the company's Web site. Marcus Ryle and Michel Doidic created Line 6 in 1996 when they spun it off from their earlier venture, the now defunct Fast Forward Designs.
