    Perfect for amp sims and preamps

    I place my OX Stomp after my preamps and amp sim pedals for playing with headphones or recording direct through an audio interface.

    Quilter Aviator Cub (Tweed/Blonde/Blackface Fender) from effects send (line out has it's own cab sim which can't be disabled, and sounds odd combined with the OX speaker cab sims)

    Quilter Superblock UK (Vox/Marshall) effects send, or through XLR out, setting it to FRFR mode.

    These are solid state amps that sound great in the room, compared to any other solid state amps I've used, but the OX Stomp really adds the magic to their direct signals.

    I've also had great success with Joyo American Sound and Joyo AC Tone amp sim pedals, and their cab sims don't seem to cause the same weirdness as that of the Quilters. Combine the crazy ranges of tones in these amps and pedals with the amazing sounding rigs in the OX Stomp and there's a lot of tonal directions to go. I even sold my Line 6 HX Stomp because I found myself playing this way more often.

    Oh and I had some app connection issues with the Del-Verb, but not the OX Stomp. I'm using an older iPad Pro. Once I got the 6 rigs set up how I want to compliment my different guitars and preamps (some bright and clear, some fatter, warmer, thicker), I don't need the app very often.

    A game changer pedal for my tone

    I bought this to expand the versatility of my pedalboard and to improve the tone of my Ruby and this thing surpassed all my expectations. The sounds coming out of this pedal are simply beautiful. My guitar tone now feels real and more 3D sounding, with depth. The amount of tones in this box is huge.

    Regarding the app, I haven't had any issue so far in my 2nd day of ownership (knock on wood) on my iPhone 13 but it seems I'm in the minority here. I'm turning off auto lock and everything is connecting and staying connected as it should. The faders are clunky, it needs numerical values so from a usability perspective there are improvement areas. But overall I'm extremely happy with my purchase, to the point that it's making me reconnect with my instrument and ideas are just flowing to my DAW. Inspiring sounds are the seeds to great ideas and this product is helping me with that. I highly recommend this pedal, It will elevate your tone.

    Turn OFF mobile screen lock = ( one) connection issue less

    Most have probably already done that - but if someone havent or just bought the product - and wants to minimize one connection issue TURN OFF the Iphone Screen lock when using the App via B.T.

    And... Please UA - MAKE UA GREAT AGAIN - let the USB be used with a new desktop for App PC / Mac !

    Its a great sounding and design with included effects , but, as said ..... MAKE UA GREAT AGAIN

    Great cab pedal.

    This pedal sounds awesome, there's a bunch of bad reviews for the app and bluetooth but all of the uafx pedals have those issues, and I agree with the 6 cab slots being a little insufficient, hopefully they can reprogram it to where maybe when you hold the preset button it can make the 6 slots more with like an A/B side , then it would at least be 12. Or have the on and preset button have an up or down functionality to it, and definitely a desktop app, there's too many phones with different firmwares to run great on every one, I personally have to touch mine every 10 minutes since I can't turn off sleep mode even in developer options so it can the frustrating. That being said the sound quality is awesome, I have multiple effects processors with different paid impulse responses and as I do like a quite a few of them , they didn't even come close to how many I like with this pedal. The reaction, sound and feel just blew me away, I do wish they would add a noise gate to this and some of their other amp pedals like they did with the lion so you can crank up the gain and go to town, I put 2 gates after the ox for high gain scenarios and it works great.

    Frustrating

    Great sound and possibilities. Here is the problem, you have 6 rigs/preset spots. Great if you like those 6. In the app however there are a bunch of really great presets and also a lot of tweaks, eq, mics cabs, awesome.... Except the app never works!!! You get it to connect after several attempts, device goes to sleep while demoing your changes, you guessed it, you have been disconnected and have to try and connect to the pedal again. Finally get it to connect again and go to make some eq changes, it just disconnects while accessing the page. I am by no means a UA hater, I have most of their plugs and have tried all of their big pedals. Same issues amongst all of them and have had multiple devices. UA seems to not think the problem exists or maybe they cant fix it. Bottom line buy them if you are happy with the default settings otherwise prepare yourself for frustration. Now i have to decide if I keep losing time and creativity or return it. Sold all of my other UA pedals for the same reason by the way . Had some hope that they addressed the issue....no they didn't.
