"Headrush / Revalver"

This product is fantastic. I use it in multiple applications and it performs flawlessly. I've ran it to a tube amp (Carvin Bel-Air 50w and Princeton Reverb) and a solid state (Katana mk2) and it just sounds, regardless.And it is simple to use! It has an intuitive interface that is simple to navigate. No deep menus or complicated button combinations here, everything is right where you need it, with visual cues that make navigation a breeze.I'm currently using it at my office with headphones. Minimal footprint with maximum tonal options.

"Great Sound and Overall Value"
Verified Purchaser

I'd had previous experience with Headrush products, owning a Gigboard as well as a Pedalboard, so I had no doubt the tone/sound would be there. And it is- with the additional flexibility of Revalver amp/cab models as well as two more configuration options, the sonic possibilities are practically endless. I've always liked being able to run my guitar through two different amps, with different (or no) effects in each branch- mix an overdriven amp in one channel with a clean-ish amp in the other channel for a cool percussive chunk, and then drop the "Stereo Doubler" delay effect (one of my constant go-to's) after to see what I mean. So, a tweaker's delight that you have to really work at to get a BAD tone. And the "drag-and-drop" capability makes the whole process pretty intuitive and painless.My only quibble with the unit is the size of the touch-screen- 4" is teetering right on the edge of being too small to be usable. I don't, I think, have particularly large hands/fingers, but there were moments when I found it difficult to find the precise "spot" to get to a function I wanted to access. That's a pretty mild quibble for me, though- if I have the patience to get through all the options to find a tone I like, then I have the patience to work to get TO them.(And this is not even getting to the size of the pedal- I do wear a size-13 shoe, so that's a little iffy)Anyway, overall, discounting the screen size, I would give this unit a solid overall 5-star rating; and I look forward to, at some point, getting my hands on a Headrush Core and, eventually, the Prime.

"Holy Sh*t! This thing is AWESOME!"
Got mine last week, and man, I can't emphasize enough how awesome the Flex Prime is! It's "smol" but built like a tank! Touch screen is awesome and feels premium. The initial setup, registration and update was super easy. The Tone3000 integration works like magic! The sheer amount of DSP on this thing is INCREDIBLE, if you can imagine it, you can have it as far as rig construction goes.The NAM A2 captures sound incredible (just be sure to get your captures from trusted creators like Tone Junkies or the Worship Tutorial guys), the ability to load up to four IR's IN STEREO IN ONE BLOCK is pretty amazing (Along with using split signal paths and running two stereo Amp Blocks on each path... Bonkers, absolute insanity! And what's wild, is even with complex rigs I create, I still have PLENTY of DSP left in the tank. Don't sleep on the ReValver amp models either, I bring this up because currently you can only upload One NAM capture in a rig, Headrush is looking into changing that but for now, it is what it is. The ReValver amp models sound awesome though and you can run two amps at once in stereo in one amp block and still have more than enough DSP to run a NAM Capture, IR and effects.This leads me to the effects side of the house, the Effects here on the Headrush are good, like REALLY good. However you kind of have to work to get ambient/worship sounds, the delays, mods and reverbs are superior on the a Line 6 unit. But what you can do with effects on the headrush like changing their EQ and mix percentage outside of the effects parameters is wild and super useful. You CAN get those lush reverbs and delays, you just need to work to get there a little more. Pitch effects are really good, not great IMO, like it tracks AMAZING going down pitches, but the up pitch can get a little wonkey (it's still VERY usable btw, not as accurate as the Poly Capo on the Helix).Also full disclosure, I am coming from Line 6 Helix land so a lot of the abilities the Headrush has that Line 6 doesn't really made an impression on me. The workflow is intuitive and fun to use, and there is something cool about having effects blocks that look like the pedals/amps they are emulating. As a long time musician, I like seeing that a lot.The web based rig editor is also amazing! I can run this on any OS (even Linux) since it's web based so no need to download OS specific software. The midi capabilities are great and straight forward to understand. There also seems to be a little confusion on the amount of scenes you can have in a rig (Snapshots to presets for my L6 peoples). The Flex Prime states you can have 6 total scenes per rig, but each scene has two different states you can toggle to. So really you can have up to 12 total scenes. And for someone who's going to put this in a rack and have everything controlled by mapped midi changes, this is SUPER clutch (especially for pro acts). You can even gig this thing on it's own. You can assign a scene to a footswich and toggle between two states of that scene which gives you a ton of versatility in just having three footswiches. The expression/volume pedal is small but VERY smooth and stable, has a very good sweep and feel.Again for less than $500 bucks you get a legit professional rig that can do everything. I'm not shocked that these things were flying off the shelves when the Tone3000 Firmware update happened. But guys/gals, it's so much more than that. The engine underneath the hood is a legit V8 and priced at a point where 4 weeks of plasma donations can get you one. You don't need to eat ramen for weeks or feel guilty after buying this guy. It does so much more than any modeler in this class and price range. Seriously, if you are curious just go ahead and pull that trigger. I promise you will not forget it
Sound
Sound Quality is almost outmatched. ToneX V2 is on the same level. Seriously those NAM A2 Captures sound amazing on this machine
Features
Not a least useful feature but I wish this guy had full sized MIDI In/Out, it's cool that it has it with the 3.5mm jack, but buying a dongle is kind of a pain.
Ease of Use
It's super fast and easy to get great sounds from this unit. The UI/Interface is super easy to understand.
Quality
The Flex Prime feels super premium, the touch screen, the metal construction and the solid feeling volume/expression pedal make it feel like a product that cost twice as much if not more
Value
This product would be a steal at twice the price. It's wild that they are selling for less that $500 bucks
Manufacturer Support
Headrush's customer service so far has been great honestly. They get back to you quick if you have a question or concern and their resources/community is legit fantastic
The Wow Factor
this is easily a 10/10 product. Highly recommend to anyone looking for a multi-effects unit. In fact, already convinced two other friends to buy one!

"Small and Powerful"
Verified Purchaser

I've had the Flex Prime for about a week, it's very easy to use. I basically upgraded from the gigabourd unit which I've had for years, and I wanted access to the NAM files. It very easy to use and capture and access files from the cloud. It's built solid, simple to use, and it sounds really good. I'm an amp guy and have many many heads and cabinets and this allows me to have all on my personal amps, cabinets, and pedals wherever I go, plus access to hundreds more. If your looking for simplicity and durability you have it in the Headrush Flex Prime. Thanks zZounds for another great purchase experience, and the last 15 plus years of service.
