Fantastic Effects Processor
It's got loads of amps and effects that are way too complicated for my brain and cover all the bases well as far as I'm concerned. I find the user interface excellent being a touch screen and knob combination. It was very intuitive and didn't require looking at the manual at all. Important to me is that I wanted a built-in, well implemented looper. This is something that most reviews and YouTubes don't cover. Line 6 (Pod Go, HX Stomp) don't do good loopers in theirs. The Headrush has a permanent, always available looper - at the time of writing, my understanding is that Line 6 require you to place a looper block into the particular patch you're using. This takes up a processing slot and has to be done on a per patch basis. It is also limited to a max of 80 seconds. The Headrush looper is always available and can record up 50 layers up to 5 mins per layer and a total time of up to 20 mins I believe. You're free to change patches between recording layers. It's not a multi-functional looper like BOSS RC-500/600 devices but is great for capturing ideas. It can be connected to the laptop to allow loops to be moved either way. It doesn't have any built-in rhythms like some such as Zoom but you could transfer a WAV or MP3 drum beat via USB and have it as layer one of a loop. You could play stuff through the AUX In but having something controlled via the footswitches is better IMHO. For example, the WAV or MP3 could be an entire song minus your guitar bit which you can then jam/solo over and capture your genius as a new loop layer. You can also record as either pre- or post-processing which, if set to pre-, would allow you to record the clean signal so then when you play it back it will play through whatever the current patch is. This would allow you to take your riff and try out different patches without having to play it again and again. Yes, I would have liked a few more footswitches but that's the way it goes (you could pipe in a MIDI footswitch for some extra control but that'll probably cost you half as much again). The software allows you a lot of flexibility in how you want to configure the footswitches e.g. on/off stomps, patch changes, scene changes, set list changes. I like having the expression pedal. It doesn't get used much but I didn't want to have yet another external expression pedal hanging around when the occasional funk fix is required. Auto Wah is always terrible so the only way to get good wah-wah-ing is to use a pedal in my view so having it there is great. The pedal is small but has a very good movement and weight to it. Very solid (and tension can be adjusted). The whole device is nice and compact, very sturdily built and fits in a gig bag pocket a treat (the sticky out ones, not the flush zip ones). Personally, I couldn't be happier and wish I'd bought it sooner.

The best compact multi effect pedal on the market
I was looking for a multi effect pedal & researched all the available models. I wanted something quite small but feature packed & one which had great amp models & effects. Upon finding the headrush, I saw it had a 5 minute looper, a practice mode, owner clones which they upload to the cloud, bluetooth & WiFi, basically an endless list of everything you could possibly need. I don't have anywhere local to try one out so looked online. Prices were all pretty similar & with it being pretty new, used ones weren't available. I did however get one here, that someone had returned, with a great saving. I paid £326 & this is an absolute bargain. Having used it, the retail price is a bargain for what this little box of tricks can do. It's easy to use, sounds fantastic & the headrush cloud has lots of available amps, rigs & pedals. You can basically have any sound you want, with the tech of a pedal. A recent update came out, version 4.1 with more effect pedals & a better cloning tool for those who want their amp sound in a box. All in all I'm delighted with my purchase. It has every function I could possibly need, it's built like a tank & small enough to put in a gig bag. With every guitar sound you can dream of, it's versatile for any application. I'd happily pay full price for one & if this one got stolen, I'd buy another right away.

Massive sound from such a small unit.
I have used the Line 6 Helix and Boss GT1000 which also sound amazing, but for some reason, I like the sound and workflow better of this. They have somehow shoved the same capabilities of the full size unit into this….how? I don’t know, but I love it. Throw it in a backpack and go. My only niggle is the power adapter- it seems a little cheap and flimsy, so if you are using it for gigging, be careful! Editing is a breeze and in my opinion, this unit has the most useful presets out of the box. If you like using a looper, Headrush excel In this department. All in all, a super unit!

Pretty good.
I have a Helix that I have never got on with so thought I would try one of these. It is much simpler than the Helix but it sounds better to me. The touchscreen is great, really easy to use. If you can get by with the three switches then I think this is a great little device, if you want more switches then get one of the other Headrush devices with more switches as the midi implementation is not great for controlling from a midi footboard.

Great sounds but such a tiny expression pedal makes it difficult to use properly
This pedal does have some great sounds built in but what let’s it down is the tiny expression pedal, admittedly they where trying to keep a very small footprint but the pedal could do with a pullout heel section so your whole foot is in control but then it may need pullout stabilisation to stop the pedal tipping, nice pedal but not for me.

Después de estar 3 años con el MX5 , hace poco adquirí el FLEX PRIME, ya que me gusta el formato de 3 pulsadores, si no necesitas pedal de expresión puedes tener un 4 pulsador disponible. Para usarlo en directo tengo una carpeta de SETLIST para cada concierto y presets de cada canción y con la posibilidad de tener 6 escenas por preset, que ahora con el FLEX PRIME pueden ser hasta 12. Mejora en todo a la versión anterior: - Mayor cantidad de huecos para colocar efectos(14) con la posibilidad de ecualizar gráficamente cada efecto o amplificador sin necesidad de usar un hueco para agregar una EQ (eso solo para mi es un motivo de peso para adquirirlo) - Mayor cantidad de escenas: 2 grupos de 6 escenas pero con el inconveniente de desactivar el pulsador de afinador, que igualmente se puede activar navegando en los menus, pero lo veo impracticable para directo. - Simulaciones de amplificador del REVALVER que mejoran mucho la calidad de las anteriores simulaciones, que ya eran bastante buenas, con la pega que no aparecen algunos amplis más típicos como el JCM 800 o el SLO 100 que usaba bastante, he tenido que ir a un PEAVEY 6505 y un DIEZEL, pero vamos para mi compensa con creces el poder usar Revalver y siempre puedes cargar un clon o super clon. - Conectividad mejorada, con bluetooth y wifi que permite incluso conectarte con una tablet por la red wifi compartida y poder ajustar los parámetros sin tener la pedalera en la mesa como con la MX5. - Libreria on line de donde descargar más efectos y amplis clonados.

I love the tones I hear on recordings of my favorite guitarists. THOSE are the sounds I want to hear when I’m playing. So my new ‘rig’ is a powered FRFR cabinet being fed by a digital modeler front end. I tried the $399 Tonex unit and found it mostly excellent except that it isn’t a true modeling amp but rather a unit built around specific tone samples. Some were fantastic, others much less so. The unit also had a handful of basic effects to complement those samples. In contrast, and for only $100 more, the HeadRush Flex Prime uses meticulously crafted models of LOTS and LOTS of actual popular amps, effects, cabinets and IRs too. I finally have the full spectrum of guitar tones spanning from the 50s through today, accurately and faithfully reproduced, right down to the feel of how the tones respond to my fingers, pick, dynamics and note muting techniques. I am currently feeding it into my Spark FRFR cabinet and it sounds terrific, and ay all volume levels too. Getting satisfying, album-like tones at low volume levels is one of the benefits of using a FRFR based system. A conventional tube amp has to be cranked to ear-splitting levels to get the tones we crave, but that our wives and neighbors hate to also have to listen to. This unit supposedly has the exact same technical innards and sound models as the bigger, more expensive HeadRush units, and each tonal patch allow up to fifteen ‘blocks’ including an amp and cab, and are almost endlessly tweakable, but easily and in instantly musically ways. I’ve had it now for about a month and have already created the dozen or so patches I need to cover 90% of what I need. The learning curve is about an hour, but the combinations of tonal elements near infinite, and so I’ve barely scratched the surface. But the results are accurate, satisfying and most importantly, INSPIRING! You just want to play for hours! But it doesn’t stop there. Included is their ‘Revalver 5.0’ software, a program where you can modify amp models’ internal circuitry and build rigs that can ultimately be transferred to your physical unit. There’s also their ‘Amp Cloner’ software for capturing your own amps’ tones should you have a specific amp sound you’d like to take everywhere you go without having to lug your heavy tube amp head/combo and half/full stack. I’m just getting into these so look for a follow-up review in another few months. Is the experience the same as standing in front of a raging stack blasting at 120 db while your pant legs flutter? No. But in my mind it’s better. You get to hear the tones you’re actually chasing, like you hear on the albums, at any volume you want. And they sound right because this little box has accurate models of the amps that created them, not just the one or two tones your stack provides.

Cambie del helix stomp a este, si bien son un poco diferentes, este tiene las mismas funciones mas la pantalla táctil, es fácil de usar y en cuanto a sonido asemeja mucho, es de calidad con el plus de tener menos parametros pero los que tiene suenan increible! No me arrepiento del cambio
