The little brother

With the HX Stomp, Line 6 has packed all the sonic capabilities of its renowned Helix into a compact-sized pedal. The result: A pocket-sized all-in-one digital system for ambitious guitarists and bassists. In terms of hardware, the HX Stomp simulates the core elements of a conventional setup: Amps and miked cabinets and both upstream and downstream effects of all kinds, which of course can be stored and configured as desired. The HX Stomp’s high-performance signal processor enables it to generate two complete signal chains comprising amplifier and cabinet models or to act as a versatile multi-effects unit – and the pedal can even be used as a USB audio interface.

A pocket-sized guitar rig

The HX Stomp includes first-class simulations of 62 amp channels, 37 speaker cabinets, 17 microphones, and more than a hundred effect types. And thanks to the powerful signal processor, it is even possible to create two separate signal chains, making a storable complete system that fits into your pocket. The HX Stomp’s authentic-sounding tone is achieved using sophisticated component modelling, and third-party impulse responses for the cabinet simulations can also be loaded. The colour display makes operation straightforward, while the unit’s surprisingly extensive connectivity makes it easy to integrate into a wide range of environments, including USB connection to a computer for recording projects. The HX Stomp is easy to operate despite its small dimensions, and it can also be configured from a computer using the corresponding free editor software.

A turbo charge for guitar and bass

The HX Stomp comes into its own whenever you need a comprehensive selection of amplifier sounds and effects – including storage capability and both MIDI and real-time control – for live applications, during rehearsals, or when working out musical ideas. What is more, the HX Stomp’s immense range of amplifier simulations and effects make it ideal for multiple different musical genres – from top 40 cover to Djent Metal – and is also suitable for bass guitarists. And last but not least, the HX Stomp (which receives regular updates from the manufacturer) is also a great choice for use with keyboards and line-level instrument signals.

About Line 6

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.

A universal enhancement and safety net

The HX Stomp is a practical all-in-one solution for recording your ideas, and it’s ready to go whenever you are. On stage, it is capable of replacing an entire amplifier setup and thus ensuring a consistent sound from night to night while eliminating the stress factor and also offering an impressive range of different tones. At the same time, however, the HX Stomp can be used as a safety net or a recording output with cabinet simulation, or it can be added to an existing setup as a source of supplementary sounds and effects.

In the spotlight: Component modelling

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.

Great but not perfect
allanjelly 24.01.2020
I have been using HX Stomp for the past 6 months and have some remarks.
1). It's really well-built, has tons of features & the sound quality is really professional - really nothing to complain about.
2). It has some added uses - about which you might have not known:
- it is a great practice tool - on its own - you can just plug-in your headphones to it and have a good time practicing while using the simulation of whatever amp you like
- it is a really good recording interface (via USB) with ASIO/midi etc.

2). It has some minor flaws which I would like you to be aware of:
- the quality of effects is not even:
- time-based effects (reverbs, delays, vibratos, choruses etc.) are simply superb;
- amp simulations - are really great - but require lots of effort to sound right - they just don't work like real tube amps which tend to sound ok at all the settings. These simulated amps CAN sound great - provided you found the settings which suit your guitar, pickups and playstyle. And believe me there are a lot of settings that can be set wrong.
- noise gate - it' simply is there - but it's really nothing sophisticated or special
- looper - it's there but the buffer is really short
- overdrives/distortions - I still prefer the real counterparts. Maybe I still did not find the correct settings? For me they do not sound ok - they do not clean up as they should and the tone/texture is simply is not there

- you really cannot use a standard power source from your pedalboard - you have to use the one provided with the unit - it is a 3000mA source. Not a big problem, but adds some mess to your pedalboard.
- you have to be good at word puzzles to use this one - due to copyright issues - example? What is "$$ for nada" preset?
Dire Straits - Money for Nothing :-) What is "2/3 beards"? - ZZ Top
Sometimes you will guess sometimes you will not - but this does not make the life easier.


Awesome product. Changed my all analog rig.

Hi, first of all i want to say that i fought over having digital stuff in my rig. I was a tube amp guy, expensive boutique pedals, expensive pedalboard, good cables, stereo routing, etc etc. But the truth was that i was always afraid of the amount things that could fail in a live situation. Unfortunately that happened and it was really frustrating. So after years i finnally decided to give a try and i bought the Stomp. The goal was to have a reliable pedalboard, with great sound, no more tons of cables, something almost plug and play. The first impression when i got the Stomp was how tiny but sturdy and weel built it was. Also very good looking. i tried some factory presets trough the PA system and i knew instantly that it would soung as good as my analog rig. Of course that some tweaking had to be made but he sound was there. At the present moment and after some rehearsals done and exploring the Stomp i have to say that my rig chanved completely. Now it?s Guitar into STOMP, midi switcher that i had already and an expression pedal (very needed in order to have flexibility, options and to take advantage of the full optential of the Stomp) straight into de mixer and PA systems. No more Amp, cabinet, pedalboard, mics and spare tool kit. It?s my guitar and my case with the Stomp in it. Simple, light, reliable and with a 3D sound as i?ve never had!
Also the software is really really user friendly. One of the best if not the best.
Don?t compare this with Helix floor. Their purposes are different. The only downside is that right now you only have 6 blocks. i can manage with that perfectly. Line 6 has confirmed that is going to release an update which allows 8 blocks. It?s going to be awesome and enough for 98% of players.
And the price for this little and powerfull tool is a must. So much money spent in boutique...not worthy.


Perfect pocket solution for recording, rehreasing and live playing
BananaGuy 13.08.2020
Ok Here is little story. I've tried lot of units. I originaly started with pod hd500x back when it was the hottest modeling unit out there. Then I started to experiment with other units and effects, went through Boss GT-100, TC electronics nova system, analog effects pedalboard, back to GT-100 and then Helix and Helix LT came out. It was perfect. Had everything I ever needed but it was little on the large side of floor units. So I sold my Helix LT and tried smaller Boss GT-1000, which was, for me as Boss fan, one of the greatest let downs ever. I was back with large and for my three and half (ambient clean/drone sound, overdrive, hi-gain) simple presets overly capable Helix LT. So what now?

Long story short, I sold the LT and bought this little piece of greatness.

There are few things worth mentioning if you are still deciding on buying:

1) It is built like tank. No bendy, soft sheet but thick casted metal stombox
2) Sound quality of amp models is, as with whole Helix family, exceptional
3) Controls and UI are amazingly intuitive. You really don't need to use PC to create sounds (except for updloading IRs)

And some little flaws I just mention so I won't sound like payed Line6 fanboy:
1) It gets warm after some time of use - lots of circuitry cramped in small metal box
2) Some of the effect models are little lacking compared to others
3) Powersource is almost as big as the unit itself and you can't use your pedalboards powersource out of the box thanks to HX stomps power demands and inverted polarity. Might be issue if you want to use it as part of bigger pedalboard.
4) It really could use some controls cover or software lock to prevent accidental switching when you misstep.

I use it for both home recording and live situations and if you are looking for all-in-one pocket solution or want to expand your pedalboard look no more. This thing is no-brainer.


Perfect for my compact pedal board build!
Rain214 27.08.2019
There's really nothing more to say about this amazing HX Stomp. Before I have this Mooer pedals for my modulations, it sounds good also and very small which is I like because I want to have a small pedal board that is easy to carry when travelling. But I decided to change it with this HX Stomp as it has a lot more to offer than just the modulations. It's Amp and Cab simulations are so awesome, that is also another main reason why I got this baby. I used the FX loop to integrate it with my Flyrig RK5, and Dunes OD and all the modulations, compressor, and Amp&Cab sims from the HX Stomp make everything sound so complete. And the tone from my pedal board is really really awesome. Tweaking the HX stomp is really easy but it is much easier with the the software that can be downloaded on the Line6 site called HX Edit.

-The Stomp is very well built, really cool looking device and it does what it should do, you can also use 4 cable method on it, Stereo or Mono and integrate it with the existing analog pedals on your board by using the FX loop's Send and Return.
-Not that heavy and it doesn't feel cheap.
-Value for money.
-The possibilities on this device are endless.

-The power adapter is nice but not good position if you want to plug it under your pedal board, that is why I got the current doubler so that I can plug it in my existing pedal board power supply. It says that it needs 3A but it runs under 1A when it is powered on so I use to 9v on my board's PSU with both 500ma each isolated and it works perfectly.
