Origin Susan Wolf together with Marcus Ryle and Michel Doidic (two former
Oberheim designers) co-founded Fast-Forward Designs, where they helped develop several notable pro audio products such as the
Alesis ADAT, Quadraverbs and QuadraSynth, and
Digidesign SampleCell. As
digital signal processing (DSP) became more powerful and affordable during the 1980s, they began developing DSP-based products which would emulate the tones of classic
guitar amplifiers,
cabinets, and effects. According to Ryle, the name "Line 6" came about because the phone system at Fast-Forward Designs only had 5 lines. Because the new guitar-related products were developed in secrecy, the receptionist used "Line 6" as a code word of sorts, and paging them for a call on Line 6 meant to stop any guitar or amp-related sounds so that they would not be overheard by other Fast-Forward clients or callers.
Launch and success Line 6 launched in 1996 with their first digital modeling amplifier, the AxSys 212, a combo amp using two 12" speakers. and in 1998 by the modeling software Amp Farm, which became popular among music producers and professional guitarists using
Pro Tools. Fearing that digital modeling was beyond the reach of ordinary guitarists, Line 6 sought to design an affordable, simple, standalone guitar amp and effects modeler with a unique look. as well as their "Stompbox Modeler" series of modeling effects pedals with the DL4 Delay Modeler and MM4 Modulation Modeler. performing with a Line 6 Variax acoustic guitar. In 2002, Line 6 introduced the
Variax line of
electric, acoustic, and bass guitars. In early 2008, Line 6 acquired X2 Digital Wireless, who had introduced digital wireless systems for guitar. Further developing this technology, Line 6 developed and introduced a family of digital wireless microphone systems in 2010. In light of increased market competition from companies like
Fractal Audio,
Kemper, and
Neural DSP, Line 6 launched its flagship modeling effects unit, the Helix, in 2015. The Helix has since expanded into a successful family of products. == Notable products ==
