Line 6 presents the Helix, a complete digital system for guitarists that simulates the core elements of a conventional setup - amplifier, speaker cabinet (and the microphone placed in front of it), and effects placed before and after the preamp - all while letting the user configure and store their settings however they wish. Players can even integrate real pedals into the system using the four send/return loops. The Helix's powerful processors feature four stereo signal paths, enabling the user to create complex soundscapes that can be utilised by both analogue and digital means as well as via USB. The user interface, which includes a large colour LCD screen together with smaller individual displays for the footswitches, also delivers outstandingly intuitive operation.
The Line 6 Helix features high-quality simulations of 62 different amplifier channels, 37 speaker cabinets, and 17 microphones as well as more than 100 effects. Thanks to its dual SHARC processors, the Helix enables the creation of complex presets using up to four signal chains, which in the past would have required immensely heavy and expensive rack assemblies. Authentic sounds are achieved using sophisticated component modelling in combination with impulse response-based cabinet simulations. In addition to the unrivalled ease of operation provided by the Helix's user interface, its extensive connectivity also lets the user control external devices, and the unit can optionally be configured using a computer by means of the dedicated editor software, which is available free of charge.
It goes without saying that the Line 6 Helix has a lot to offer musicians who perform live, but the benefits for recording studios and home studios are also many. Its immense selection of amp simulations and effects also means the Helix will capably handle any conceivable genre of music, from top 40 hits to Djent Metal, and the range of potential applications goes beyond electric guitar: The Helix is also suitable for amplifying electric basses and acoustic guitars, and it can additionally provide effects for keyboards and other line-level instruments. What is more, Line 6 issues regular updates with additional amp sounds and effects, so the range of possibilities is expanding all the time.
The American manufacturer Line 6, which has been an affiliate of the Yamaha group since 2014, is one of the pioneers in the field of digital amplifiers for guitarists. The company was founded in 1996 and, that same year, presented the world’s first digital modelling amplifier: The AxSys 212. The breakthrough came in 1998 with Line 6's POD, which made sound modelling available in home studios for the first time. Since 2015, the Helix series has provided even more refined simulations. The Variax technology has additionally allowed the Californian firm to model electric guitars sounds with ever more flexibility. Besides effects pedals, Line 6 also offers software and recording technology, and is active in the field of digital wireless systems for sound transmission and small PA systems.
As mentioned above, the Line 6 Helix offers guitarists and bass players a universal solution which, despite its compact dimensions, can replace an entire amplifier setup. This means that players are ready to record whenever and wherever they like, as well as having an immense range of sounds at their fingertips on stage without the volume and sound consistency issues associated with real amplifiers picked up by microphones. At the same time, players can use the Helix as a high-performance effects processor and speaker simulator to enhance the sound of amplifiers they already have, and its four programmable effect loops, MIDI control capability, and astonishingly clear and intuitive user interface make it ideal for use as a central controller for external hardware.
In component modelling, a real circuit is measured one component at a time and digitally emulated with precisely the same characteristics. This allows an exact analysis of the installed components’ individual properties, actuation, and characteristic curves to be made, which results in an overall sound that is closely based on a specific original instead of on a generic circuit diagram, and its responsiveness and playing dynamics are also astonishingly authentic.
