Helix Rack is a new kind of guitar processor. It’s not only a tour-grade rack-mounted multi-effects processor that sounds and feels authentic, it’s also one of the most comprehensive master controllers for guitar systems ever built. Start by recreating the tones in your head with the new HX modeling engine—the new amps, cabs, mics and effects will feel familiar to anyone who has ever spent time in the studio getting the best guitar sounds from both vintage and modern gear.

Have a pile of oddball pedals that you rely on for your personal sounds? No problem. Take advantage of the most comprehensive I/O and routing capabilities ever built into a multi-effects unit and easily integrate them into the Helix Rack environment. Once connected, create custom setups that make your external pedals feel like they’re all under the hood. Whether you spend your time in the studio or on the stage, Helix Rack is the next-generation guitar processor you’ve been waiting for.

Real tone that feels and sounds like your analog gear
When it comes down to authentic sound and feel, Helix Rack represents a giant leap forward for guitar technology. The dual-DSP engine provides massive power to accurately recreate the dynamic feel of tube amplifiers, not just their sonic fingerprint. Each stage of an amp's circuit has been measured and matched back to the original, so that each model reacts and interacts just like the real thing. This level of dynamic circuit detail extends into areas like power supply ripple, individual tube sag and control over B+ voltages. Once these elements are captured, you get classic bloom and gooey compression on some amps, and a powerful gut punch on others. Helix Rack also lets you load custom impulse responses, allowing you to personalize your rig setup.

Smart interaction—so intuitive you already know how to use it
Massive power traditionally comes with a steep learning curve, but Helix Rack challenges that way of thinking. The 6.2" 800x480-pixel LCD display all but eliminates menu diving and provides the same level of control you would expect from an external editor. When it comes to creating tones, Helix Rack is as fast as you are.

Speed up your editing with Helix Control
Helix Rack can be controlled by almost any MIDI-capable device, but adding Helix Control gives you the same innovative capabilities found in the floor-based Helix, and this means that—for the very first time—you won’t have to stop playing to tweak a knob. With Pedal Edit Mode, you can edit any parameter you like using your foot: simply select the block that you want to tweak, and its parameters spill out onto the Helix Control footswitches. Select a parameter, and tweak the value using one of three optional expression pedals.

Helix Rack has four stereo paths per preset, allowing you to design complex routing scenarios for each patch. Creating variations on wet and dry routing schemes is as easy as loading a template or tweaking the joystick, and using the onboard effects models in conjunction with the four freely assignable effects loops means that the tonal possibilities are truly huge.

Control of your entire rig—integrate and control internal and external devices
As the most advanced guitar processor ever made, Helix Rack can become the nerve center for your entire guitar rig. Easily integrate traditional effects pedals and other hardware into your environment, creating a seamless hybrid rig that incorporates the best of what software and hardware have to offer.

Helix Rack has extremely flexible audio routing thanks to its dynamically allocated DSP. Use the four effects loops to connect four separate pedal chains, or split them up and use them as freely assignable inputs and outputs. In combination with four stereo paths, this means that you can process multiple instruments at once, send wet and dry signals to different places, and create large integrated systems that take advantage of both digital and analog I/O at the same time.

When you need to incorporate external devices via MIDI, Helix Rack offers more flexibility than any multi-effects unit ever. In addition to powerful real-time MIDI control, Helix Rack can send up to six separate commands at patch recall that aren’t assigned to a connected footswitch, which means you can change a patch on a synth, start a sequencer and turn up a fader on an external mixer, all with one patch recall. Add AES/EBU digital I/O, Wordclock sync, support for three expression pedals, CV/Expression out and external amp switching, and Helix Rack can be the command center for any size rig.

Helix Foot Controller
Helix Rack can be controlled by almost any MIDI-capable device, but with the included Helix Control Floor Controller, you the same functionality as the floor-based Helix, opening up a new world of creativity. With Helix Control connected over a single cable, Rack users can select a block for editing by touching a footswitch, create custom labels for the scribble strips, connect up to three expression pedals, and edit parameters hands-free for the first time using Pedal Edit Mode.

Capacitative Touch Footswitches
Helix is an incredibly fast tone creator, giving you the ability to touch a footswitch and quickly tweak parameters or easily assign or learn controllers. Instantly jump to any block simply by touching the associated footswitch. It’s so fast, you can comfortably assign any item to a switch in three seconds.

Powerful Master Controller
When you need to incorporate external devices via MIDI, Helix offers more flexibility than any multi-effects unit ever. In addition to powerful real-time MIDI control, Helix can send up to six separate commands at patch recall that aren’t assigned to a footswitch, which means you can change a patch on a synth, start a sequencer and turn up a fader on an external digital mixer, all with one press of a footswitch. Add two additional expression pedal inputs, CV/Expression out, and external amp switching, and Helix can be the command center for any size rig.

VARIAX Control Enhancements
Helix 2.0 firmware features new Variax control enhancements that open up new performance possibilities. Toggle between two guitar models with a footswitch, control the Variax tone knob with an expression pedal, assign a momentary footswitch to drop D and more.

As Easy to Use as Helix
Helix Edit features the same accessible and intuitive user interface as Helix itself, so there’s no need to learn a new workflow. Reorganize your patch list, rename patches, edit tones and customize footswitch labels quickly and efficiently. Drag and drop amps, cabs and effects to build complex signal chains with ease. And adjust settings and parameters using dedicated sliders and knobs.

Computer-Based Editing
Helix Edit software provides a convenient way to edit tones on your computer. Stay focused on your creative work when you’re recording with a DAW—Helix Edit is available when you need it. Simply leave Helix on the floor or in the rack and keep working at your computer. You’ll also have the advantage of viewing complex patches and intricate signal paths on your large computer screen.

See Every Detail
Helix Edit lets you visualize every detail of your tone editing workflow on your computer. See a comprehensive visual overview of your tones and settings in the Main Editor panel. Quickly browse banks, presets and impulse responses in the Librarian panel. Easily dial in the perfect live sound with the Global EQ panel. And quickly assign commands for your external gear in the Command Center panel.
