Universal Audio OX Stomp Dynamic Speaker Emulator Pedal

Get perfectly miked guitar tones in seconds.

Standing on the shoulders of their 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.

• Get three-dimensional, album-ready guitar tones from your amp emulator thanks to Dynamic Speaker Modeling:
• Experience jaw-dropping speaker, cabinet, and room emulations far beyond common IR loaders:
• Add studio-quality 1176 compression, plate reverb, EQ, modulation, and stereo delay effects for perfectly produced tones
• Audition, tweak, and save custom presets and more with the UAFX mobile app
• Say Goodbye to Static-Sounding IRs

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.

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.
