Line 6 HX Stomp Guitar Multi-Effects Processor & Amp Modeller
HX Stomp Step Beyond
HX Stomp is a professional-grade multi-effects processor that delivers the sound of Helix amps, cabs, and effects in an ultra-compact pedal. Use it as a “super stompbox, ” a backup or travel rig, an add-on tone expander when combined with other modelers, an audio interface—or even a complete guitar or bass rig. The same HX Modeling technology that powers the flagship Helix guitar processor enables HX Stomp to run up to six processing blocks simultaneously, making it the most powerful and flexible stompbox-sized multi-effects processor available. HX Stomp is easy to operate, however, thanks to its simple-but-powerful controls, 320 x 240-pixel color LCD, and capacitive-sensing footswitches with color-coded LED rings. External control via MIDI and optional expression pedal and footswitch control provide additional flexibility, as does I/O that may be configured for sophisticated routing such as simultaneously feeding an amp and a FOH mixer, 4-cable method operation with an amplifier, and studio re-amping. Along with 300+ Helix amps, cabs, and effects—even a looper—HX Stomp includes a legacy library of effects from Line 6 M-Series pedals, as well as from classic Line 6 stompbox modelers such as the DL4, MM4, FM4, and DM4. There are also presets created specifically for bass players, as well as individual bass amp and cab models. The free HX Edit app offers preset librarian functionality and third-party IR loading.


Explore Features:
AUTHENTIC TONE
The SHARC® audio engine in HX products accurately recreate the sonic characteristics and dynamic playing response of classic and modern amplifiers and effects.
HX CABS/IMPULSE RESPONSES
Helix cabinet models provide low-end reproduction and overall definition equivalent to a 2048-point impulse response (IR), and third-party impulse responses may also be loaded.
COMPONENT MODELING
Each stage of an amp’s circuitry is measured and the results matched to the original during the modeling process, ensuring realistic sound and an authentic playing experience.
BEHAVIORAL MODELING
HX Modeling technology captures the unique behavior of analog effects devices by measuring their individual components, resulting in authentic recreations of even notoriously difficult-to-model effects such as germanium fuzz and “bucket-brigade” analog delay pedals.
INTERACTION
HX processors feature a clear interface that enables fast tone creation and easy interaction—all with a minimal learning curve and the elimination of complex menu diving.
CAPACITIVE-TOUCH FOOTSWITCHES
Simply touch a footswitch to instantly jump to any block and quickly adjust a parameter or assign controllers. Color-coded LED rings convey footswitch assignments and status at a glance.
SNAPSHOTS
Snapshots enable you to create multiple variations within a single preset and seamlessly transition between them, without the audio dropouts that occur when switching between presets.
I/O LEVEL SHIFTING
A switchable line-level input enables keyboardists, DJs, and producers to connect electronic instruments or use HX products as outboard processors in the studio.
ROUTING
HX processors easily integrate into pedalboard and studio rigs thanks to their flexible routing capabilities. Internal routing includes parallel stereo signal paths, while inputs and outputs include stereo-linkable effects loops.
COMMAND CENTER
HX processors can serve as command centers for any rig. MIDI messages can be sent manually via footswitches (or an optional expression pedal), and up to six commands can be sent automatically at preset or snapshot recall. Even QWERTY hotkey commands can be sent via USB.
ANALOG BYPASS
Switchable analog bypass routes signals at the input(s) directly to the output(s) without undergoing A/D/A conversion.
HX EDIT
HX Edit features the same intuitive user interface as HX processors. Create complex signal chains with ease, adjust settings and parameters using dedicated sliders, customize footswitch labels, and more.
POWERCAB
Powercab active guitar speaker systems were designed to provide an organic “amp-in-the-room” playing experience when paired with Helix, HX Stomp, or other amp modelers. Explore Powercab.
