Universal Audio UAFX OX Stomp Dynamic Speaker Emulator Pedal

Universal Audio UAFX OX Stomp Speaker Emulator Pedal Overview

Standing on the shoulders of the award-winning OX Amp Top Box, the OX Stomp Dynamic Speaker Emulator Pedal from Universal Audio delivers a full studio worth of authentic-sounding guitar cabinets, speakers, microphones, and even room spaces for any possible tone. Along with its 22 speaker cab combinations, the OX Stomp also features emulations of six vintage microphones and a full suite of studio-quality effects, including reverb, delay, EQ, modulation, and compression FX taken directly from UA’s celebrated 1176 compressor.

The speaker emulations go beyond the typical IR models, with speaker characteristics like Breakup and Cone Cry rendered in full detail. The pedal sports silent switching, a buffered bypass, and analog dry through functions as well as support for the 4-cable method via the OX Stomp’s stereo inputs and outputs. With the built-in USB-C connection, you can control your whole pedal, including its numerous RIGs, cabs, and effects, via the convenient UAFX Control app, making it easier than ever to find the ideal sound for your performance.

Say Goodbye to Static-Sounding IRs

Going far beyond the one-dimensional captures of impulse response systems, 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 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 the 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.
