Building off Universal Audio’s industry-defining Ox unit, the Ox Stomp Dynamic Speaker Emulator is a single-pedal solution for perfectly produced guitar tones. Simply pair the Ox Stomp with your preferred amp-in-a-box or digital amp modeler to elevate your tone with 22 masterfully emulated speaker/cab combinations, which are powered by Universal Audio’s cutting-edge Dynamic Speaker Modeling. Ox Stomp’s two 3-position mic switches allow you to pair any of its six vintage mic replications to achieve the recorded cab tone of your dreams, and you can also choose an additional mic for your Room control. No produced guitar tone is complete with a slew of effects, so Ox Stomp also boasts an extensive array of delay, compression, reverb, modulation, and EQ parameters accessible via the UAFX Control app. The 6-position rig knob ties it all together, giving you instant access to six of your favorite cab/mic/effect combinations. Whether you’re running a UAFX amp pedal or any other form of amp modeler, Ox Stomp will transform your tone with record-ready studio sonics!

Three amplifier modes

More than 20 legendary cabs to choose from The Ox Stomp is a comprehensive stompbox solution for perfectly produced guitar tones, and it all starts with Universal Audio’s immaculately modeled cabinet and speaker emulations. From classic 1950s combos to roaring high-gain stacks, Ox Stomp sports 22 speaker/cab combos to cover any musical application in the book. Moreover, Universal Audio’s Dynamic Speaker Modeling Technology replicates every minute sonic nuance and harmonic detail of your chosen speakers, including cone cry, speaker breakup, and even a dedicated knob to fine-tune Speaker Drive.

Six vintage microphone emulations

To attain a truly studio-polished tone, speakers are only half the battle — you will need a few mics to capture your cabs! Luckily, Ox Stomp has six spot-on re-creations of the most iconic vintage microphones in recording history. Classic ribbons, discerning condensers, and time-tested dynamic microphones — the Ox Stomp’s two 3-way microphone switches allow you to pair any of this pedal’s microphone emulations together in the configuration of your choice. Plus, the Room knob gives you the power to choose any of the Ox Stomp’s six mic models as your room mic to add a touch of breath and liveliness to your signal. Picky about your mic placement? The UAFX Control app offers in-depth positioning control over all three of your mics, in addition to thorough per-mic EQ settings.

UAFX Control app offers a studio-grade effects arsenal 

Music Experience guitarists are amazed by the studio-grade quality of the Ox Stomp’s mic and speaker emulations. Of course, one last ingredient is key to any well-produced guitar tone: effects. That’s no problem here — simply use your mobile device to pair the UAFX Control app with your Ox Stomp to access an incredible array of studio and guitar effects, from genuine UA 1176 compression to spacey reverb to delay to extensive EQ options. Once you’ve chosen your required effects, you can save cab/mic/effect combinations to the rig knob for instant access to six of your favorite tonal presets — a must-have feature for guitarists running several disparate digital amplifier models in a single show or session. Moreover, the Ox Stomp’s “B” footswitch can be configured to serve as a mirror image to the “A” side, effectively giving you six more rigs to choose from. Do you prefer a small set of rigs? Set the “B” footswitch to a variety of other uses, including serving as a dedicated on/off toggle for one of your effects. As a bonus, Universal Audio also includes 100 masterfully curated rig presets to choose from right out of the box!
