Helix
Helix is Line 6’s tour-ready flagship multi-effects modeling device. Powered by the company’s HX modeling engine, Helix lets you experience hundreds of amplifier, cabinet, effects, and microphone models in a more realistic way than ever before. Each model has been digitally re-created down to a component level, which ensures your tone not only sounds like the real thing, but it also responds and feels like it too. Helix also boasts a huge array of I/O, which allows it to be used as a streamlined controller for your existing system, an incredible-sounding guitar interface for recording in the studio, or even as a replacement for your whole guitar rig. And yet, the most groundbreaking feature of Helix is its amazingly intuitive workflow. Dialing in Helix can be done on the fly with incredible ease.
Helix Features:
- The most powerful Line 6 multi-effects unit ever
- Dual DSP-powered HX modeling engine
- Over 200 amp, cab, mic, and effects models

Helix LT
For players who demand the sound, integration, and ease of use of the original Line 6 Helix, but who don’t need all of its expansive feature set, Helix LT is the multi-effects unit to use. Onboard Helix LT, you’ll find the exact same modeling power, gear models, and streamlined workflow as its bigger brother. But by putting all that into a smaller footprint with fewer additions, Line 6 saves you some serious money while still powering your sound with tones that have been turning the modeling world on its ear. In fact, one of the main differences between the two units is the lack of Helix’s customizable scribble strips. But don’t worry! Helix LT simply moves the indicator to the bright and easy-to-read 6.2″ LCD display. And around back, you still have much of the same I/O as LT’s bigger brother for integrating into any type of guitar setup. If you don’t need the unending options of the original Helix, check out the slimmed-down Helix LT.
Helix LT Features:
- Dual DSP-powered HX modeling engine
- Over 200 amp, cab, mic, and effects models
- 6.2″ LCD display
