Get Perfectly Miked Guitar Tones in Seconds

Standing on the shoulders of our award-winning OX Amp Top Box, OX Stomp Dynamic Speaker Emulator pedal gives "amp-in-a-box" modelers a packed pro studio full of authentic-sounding guitar cabinets, mics, room modeling, and studio-quality effects — right at your feet.

Say Goodbye to Static-Sounding IRs

Going far beyond the one-dimensional captures of Impulse Response systems, only UA’s groundbreaking Dynamic Speaker Modeling convincingly emulates speaker breakup, drive, and cone cry — providing harmonics and sonic complexity indistinguishable from a perfectly studio-miked speaker cabinet.

Experience Award-winning Room Emulation

In addition to expertly placed close condenser, dynamic, and ribbon mics on your cabs, OX Stomp is the only effects pedal to offer a complete selection of room mics with Dynamic Room Modeling. This gives you the authentic experience of pushing air while recording your cranked amp in a world-class tracking room.

Enjoy Studio-Quality Effects

Beyond mic and speaker cabinet modeling, OX Stomp also lets you craft stunning guitar sounds with UA effects like genuine 1176 compression, plate reverb, chorus, flange, three delay types, and four-band EQ with high and low-cut filters.

Expand the Tones of any Amp-in-a-Box Modeler

Whether you're using a UAFX amp emulator pedal or other popular amp modelers, multi-effects, or profilers — even your favorite amp's preamp line out — OX Stomp gives you over 100 curated RIG setups, giving you inspiring sounds for any amp type or genre, right out of the box**.

Expand your Tones with MIDI Control

Using its rear panel USB-to-MIDI connection, OX Stomp fits right into your programmable MIDI rig, receiving preset changes and realtime control of effects, EQ, and more. It’s the fast ticket to live performance heaven*.

Powerful App Control with Hardwired or Bluetooth Connection

The UAFX Control app allows you to easily swap cabs and mics, fine-tune effects, assign RIG presets, and configure footswitches to instantly toggle sounds and/or effects. Plug right in with a direct "hardwired" USB connection to your smart phone, or enjoy rock-solid control over Bluetooth.

What They Say

Ox Stomp is perfect for getting a good tone with just a couple of pedals. We’ve come a long way from lugging huge amps to sessions to get a great sound!

Butch Walker

Green Day, Weezer, Taylor Swift

Ox Stomp is a great tool for practicing on the road! Along with the Lion '68 Super Lead Amp pedal, I get superior sound on the go.

John Notto

Dirty Honey

I really love the Lion and Ox Stomp! They're the only way I can really play my harp through a variety of amp styles outside of a DAW..

    The finishing touch!

    I'm a tone snob. Opinionated and always looking for "holy grail" sounds. I was very skeptical that anyone's idea of what guitar should sound like could meet my personal standards (UA - no offense! I absolutely rely on your Apollo ecosystem and plugins for my audio work.) This pedal has hit the mark. While the presets are great, I actually needed some very specific dual mono setups and was able to build stunningly realistic rigs that are fun to play through without the froggy tones of IR platforms. Thank you UA. (And thank you for the super smooth controls in the latest free app update - that was my only gripe!)

    Huge disappointment

    The quality of the speakers and mics is great - no complaint here. If it is better than good IRs is highly subjective but thats not the point. Some people like me hate the IR workflow.

    The layout of the pedal is not great. Instead of the speaker drive poti I would like to be able to control reverb and delays levels without the app. No indication of stored values. So you need the app for fine adjustments of existing presets. Connection still is a bit rough.

    But the app itself is horrible. So bad that the effects are not even really usable. Some sliders only work in the first 5%, no exact values possible for example important for the delays. It is often either too little or too much. So you are bound to use them in very simple ways... I call that false advertisement.

    What really bugs me is that UA knows all that and does NOTHING. Because of that I don´t think I will buy another UA product.

    Great products - Needs a Desktop App Pronto

    Tones are immaculate, the mobile app is a nice gimmick. But come on, this thing needs a desktop app. It's ridiculous that I have to pull my phone every time I need to adjust something. Thank you.

    Amazing Cabs + Mics + EFx

    If you care about your tone, you really should give this box a try. It is a wonderland of boutique tones for all of your preamps and amp simulators. Since I got it, my guitar recordings sound so much better -- very lifelike and 3D. If you own a Synergy system, any UA Stomp pedals, Fractal/Helix stuff, or any of the other amp-in-a-box devices (from Victory, Friedman, Two Notes, etc), this is a great match. However... I'm using it mainly for home recording. I don't know how useful it would be in a live situation, and it's NOT a load box, so it can't go directly after a tube amp head.

    Amazing

    I used this with a cheap Boss IR 2, and it is really surprising how good this thing sounds. Factory presets are great to demo how a single cabinet can change character with a few studio effects. You could easily pick a single cabinet you like for your amp sim and have six distinct preset slots by making simple changes in the app.
