Still Awesome although FW and SW need updates

This is a great product. Built like a tank and sounds great. It' s showing it age in todays market though.
Don't know what's happening upside of UA's cranium but this diamond only needs a polish via its FW and Software and could potentially remain a formidable unit well into the future. Sounds great and keeps you playing and creating! Still love it!

OX BOX is great but needs IOS updates

Hardware is amazing but you need to update your IOS software for multitasking and landscape view. Also the ability to reposition mics to different places on the cabinet.

Simply brilliant!

I’ve been using an old tube combo amp (circa ‘70s) into the OX, to a UA 4-710, into an Apollo. The variety of sounds from this simple set up is surprising, from clean to crunch, to grunge, even metal. Very well made, solid hardware.

I love my OX.
Having said that, we need a Leslie cab emulation !!!!

Perfect for guitarist home studios

I am a guitarist that has a small studio setup at home for songwriting and practicing. I’ve never been happy using amp sims and digital plugins for my direct guitar tone. The Ox has been awesome for me getting a tone I’m happy with and letting me use the amps I normally gig with. Looooove it!!!

Amazing box but needs an update!!!!

PLEASE FOR THE LOVE OF GOD, GIVE US A 15'' SPEAKER OPTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This thing sounds fantastic on the given cabs, but is years overdue for a proper update hence the four stars.

Great for computers less for loudbox

I bought this mainly to use as a loudbox and was a little disappointed, I used a couple of the best 12 awg speaker wires available on the market however going beyond position 4 the sound degrades excessively losing too much treble and bite, it doesn't can compensate with the EQ of your amp or guitar effects pedal. contacted customer service for explanations and advice they repeated "due to fletcher munson effects quieter sounds will have more midrange and less bass/treble" repeating it to me several times although I already understood it at the first, but it is not possible that it already happens at position 3 in such an intrusive way! it is unusable from 3 onwards. the difference in decibels between position 5 (no attenuation) and 4 (first level) is minimal and certainly not worth the cost of the product. I want to hope that for other speaker and amp combinations it works better than with my custom hiwatt and fane speaker. the other functions are excellent: speaker simulator, microphones, presets, output to audio interface and mac all beautiful and high quality. not to the level of the loudbox only functions.

I LOVE this thing.

What a game changer. I have this connected to my Apollo via the optical connection and it sounds SO good. Love it. Being able to use my pedal board + 3 amps and yet keep it all contained in either my headphones or nearfields is just a beautiful thing. The power soak / attenuator bit is great too, don't get me wrong, but I don't use it as much. The desktop app on macOS works great - no issues whatsoever.

Could be 5 stars, but UA has abandoned support for OX

The iPad app is long overdue for an update to run in landscape mode or be compatible with multitasking features in iPadOS. Intermittent connection issues have always been a problem with the onboard WI-FI. An update to utilize the rear USB ports for connectivity would solve many of these issues. At this point I regret not purchasing a Kemper and sticking with my old Marshall Power Brake instead

What took me so long?

This thing absolutely rules. Messed around a little with the app which was cool but have just been spending my tube with the director cabinet emulation on the unit straight to speaker. And to be honest it hasn’t left the first rig setting at all. I look forward to the ride.

경쟁자가 없습니다

출시한지 시간이 꽤 지났음에도 불구하고 경쟁자가 없습니다
잠자고 있던 앰프 헤드를 잘 사용 할 수 있게 되었습니다
최고의 제품이며 추후 펌웨어 업데이트 혹은 새로운 버전의 하드웨어 역시 기대하게 만드는 UA의 기술력에 찬사를 보냅니다

Technically challenged!

I'm sure this is a great product because everyone's raving about it! I found the manual very hard to follow and not terribly helpful. I can't figure out how to record the Ox into Cubase 10. If anyone who reads this is interested, I would gladly pay for a 30 minute support call over Zoom. Contact: or Whatsapp: +491623847955 thanks, Rick

The OX Box surpassed my expectations!

As a working guitarist I was well aware of the OX's capabilities in handling high-powered overdriven tube amps like vintage Marshalls and boutique amps like Soldanos and Dumbles and making them more manageable at loud levels in the studio. However, I wasn't sure of how they would respond to a clean full jazz tone with an archtop hollow body. Well, I was pleasantly surpised when I hooked the OX up to my blackface Fender Twin Reverb with a 1963 Gibson L5CES. Fantastic! Warm and fat with plenty of response...I rely on the sound and feel of my stage level at about 5-6 but that is not normally possible when I do my online videos and prefer to have the amp nearby. The OX more than solved my problem and mated beautifully with my Apollo Twin interface straight into OBS for video recording and Logic Pro for audio tracks. Bravo, Universal Audio! Another triumph.

It's amazing when it's connected

4 hours into a recording session. Still trying to connect the OX to the PC. Even uninstalled the antivirus... so after 23 restarts, two factory resets, and 2 flash drive firmware updates, I am still trying to find my ox while researching the fastest ways to commit suicide :-)

Great tool!

I recently had to relocate my studio from a very large space to a very small one, and as such I now rely on the OX for recording. The design is fantastic. and the bottom line is it does what it supposed to do. I'm able to use all of my amplifiers and get my work done.

that's said, The cabinet emulations don't have the dimension of recording real cabinets, but neither does any other solution i've seen for cabinet simulation. I think we're in the infancy of this technology. I hope UA will strive to improve the quality and continue updating. I love the fact that when I get back to a larger space it will still be useful as a power soak, or even direct recording when it's convenient.

Would love to see some Leslie sims added.

Overall great product!

Sounds amazing with so many choices, why didn’t I do sooner!

Loving My Ox

For the benefit of consistent recording (and to promote domestic harmony), I evaluated many electric guitar recording options and all paths lead to Ox. Great tones are easily achieved with this system. There is a wide and diverse palette of sonic options. I found the interface intuitive and easy to operate.
The packaging is also top-notch. This beast can really hold up.

Would love to see the following enhancements:

* Bass Rigs
* Moveable mic positions
* 1176 for individual mic processing - perhaps alternate comp/limiters as well
* Alternate reverbs to plate (chamber, room, hall)
* Envelope modulation option on delay (think PCM41)
* Direct Outputs of individual "mics"

Very convenient but......

I have been using some form of attenuator on my vintage Marshalls since 1980.....inspired by Tom Scholz, I had my local guitar shop build a big pot in a metal enclusure that I stuck between the amp and cab. Over time that gave way to Marshall Powerbrakes, Kock Load Box 120 and, most recently Aracom's (of the units I have tried, these were the best at maintaining tone but giving flexibility in impedance and level - both line and through the cab). For recording I have alwatys used mics but found them frustrating nad my results inconsistent - recenlty I bought a Tul G12 that massively improved the challenge and made life coparatively simple....apart from the fact that you still need to crank the amp to levels that are not always neighbour friendly when recording at home. I tried a few cab sims and really liked the ADA unit hooked up to the line level output of the Aracom but wanted something that had more choice for different amps and was introduced to the OX .

Impressiosn to date are, on th ewhole, positive. I like the ability to plug into a single box and send separate feeds to the cab, to line level (mixer) and headphones.

My only compliant is that the level control to the cab is stepped and at full level still seems attenuated. At lower levels there is definitely a loss of high end and clarity. In this respect the Aracom is superior IMO

The strength of the OX (at least IMO) lies in the cab emulations whcih has huge choice, not just in enclosure/driver combinations but in the tools to manipulate the sound (mics, speaker break up, mic position, Eq, compression, delay, reverb).I have found it very simple to customise cabs and tailor solutions for different amps/guitars/tones and mixes.)

My only complaint on the mic position is the choice limit to on or off axis. The ADA cab sim has a rotary control that allows a wider freedom of choice and I found this abilito to fine tune position a real advantage.

I do not work in a DAW ( I have an old Soundcraft analogue desk and Otari Radar) so have little experience of other interfaces, IR or other similar products but saw a number of early OX reviews that were critical becuase it did not appear to offer compatibility with the reviewers preferred or chosen IR/sim package. Whilst I can understand that frustration, I have found no lack of choice in the OX and the available tools certainly enable the user to craft solutions to their own tastes/needs.

I would like to see some additional bass cab options - I currently use a Darkglass B7K to record bass - but ot woul be great to see what OX could do with some more bass oriented emulations.

Overall, happy to recommend the OX - has made life very simple and the "next level" suggestions I have do not prevent OX providing a very convenient and easy to use solution.
