Perfectly Miked Amp Tones and Effects From a Pedal

Standing on the shoulders of the 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.

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.*

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.

Customize your OX Stomp with a Full-Featured Mobile App

With the UAFX Control app, you can easily swap cabs and mics, fine-tune effects, assign RIG presets, and configure footswitches to instantly toggle sounds and/or effects, for a pro studio's worth of tones on your pedalboard.

Add a Studio Full of Vintage & Modern Cabs and Microphones

With its generous complement of 22 cabinets and six microphones, OX Stomp gives you nearly any tone imaginable.
