Line 6 HX Effects Guitar Processor

Integrate 100+ effects from Line 6's Helix, M-Series, and Stompbox Modeler pedals into your existing pedalboard and rig with the HX Effects guitar processor.

The HX Effects processor was designed to be integrated into traditional amp and pedal setups and may serve as anything from a dedicated multi-effects unit to the command center for your entire rig. HX Effects provides more than 120 effects from the line 6 flagship Helix amp and effects processors in a compact, pedalboard-friendly format, including world-class polyphonic pitch-shifting effects.

The HX Effects processor also includes legacy effects from the acclaimed M Series and Stompbox Modeler pedals. Up to nine effects may be combined simultaneously. Eight capacitive-touch footswitches with LED rings and LCD scribble strips make it easy to edit your sounds. Just touch a footswitch to jump to any effect, adjust its parameters, or assign controllers. Extensive routing and control options provide flexibility onstage or in the studio, and facilitate easy integration with traditional pedalboards and amplifiers. A switchable line-level input even lets keyboardists, DJs, and producers connect electronic instruments or use HX Effects as an outboard studio processor.

Hear what the Line 6 HX Effects can do in our exclusive video demo:

The HX Effects processor features the same SHARC® DSP chip used in the Helix amp and effects processors and supports up to nine simultaneous effects. A 123dB dynamic range ensures exceptional depth, responsiveness, and ultra-low noise.

HX Effects features more than 120 effects from the Helix processors, including read more world-class polyphonic pitch-shifting effects, along with legacy effects from the Line 6 M13™, M9™, M5™, DL4™, MM4™ , FM4™, and DM4™ pedals.

HX Effects users can customize their sounds with impulse responses (IRs) from third-party vendors. This feature can be useful for stage/FOH routings and simulating acoustic guitar body resonance.

Helix 3.50 firmware features IR-based speaker cabinet engine and which adds 20 guitar cabs and four bass cabs with a choice of 12 microphones, and you can change their angle, position, and distance in relation to the cabs. You can even drag the mics around in space for easier and more exact placement when using the HX Edit 3.50 application.

Eight capacitive-touch footswitches with color LED rings and associated LCD scribble strips provide fast and intuitive effects selection and editing. Simply touch a footswitch with your finger to jump to any effect, adjust a parameter, or assign controllers. Touch two switches to swap their settings. Touch-hold a switch to display multiple effect parameters across the LCDs.

Robust routing and control options make it easy to integrate HX Effects into existing studio and pedalboard rigs. There are two assignable effects loops (stereo-linkable), two expression pedal inputs, and amp-switching outputs. You can also create parallel stereo signal paths. A switchable line-level input lets keyboardists, DJs, and producers connect electronic instruments or use HX Effects as an outboard studio processor.

The HX Effects processor can be the command center for your entire rig. Communicate with other pedals or your DAW software via MIDI DIN or USB MIDI, and control your amps via two dual TRS switch outputs.

The free HX Edit app mirrors the HX Effects processor interface. You can drag and drop amp/effect blocks, build signal chains, customize footswitch labels, and adjust parameters via dedicated knobs and sliders from your computer screen.

I've bought, traded, rented, and tested hundreds of pedals over the last few years. I just assumed that these multi effects units could not produce the same quality of sounds as a single pedal built specifically for the task. I bit the bullet here and went ahead and ordered one, and Im wildly happy that I did. The rig sounds absolutely amazing. I'm now able to get rid of my old style SKB box and lighten the load buy 25 some odd pounds. Within 30 minutes I had already recreated my board, and with the ability to run 9 effects in a patch, I actually got to add an always on drive! The tones are incredible, the quality of construction is very solid. I haven't even got to dig deep into it yet, but I'm more than satisfied already, anything else is just a plus. Do your back a favor. Go ahead and buy it. Amps tested through ML Signature Fender Hotrod Mess Lonestar Sounds killer on both!
