Universal Audio OX Stomp Speaker Emulator Pedal - Pro Mic'd Amp Tones

Our review of the Universal Audio OX Stomp finds it aimed squarely at guitarists who want studio-quality mic'd amp tones from a single stompbox. The bottom line: this pedal brings the core of the award-winning OX Amp Top Box into pedal format, giving players convincing speaker emulation, flexible mic and room choices, and high-quality effects that dramatically improve amp-in-a-box and modeler rigs. It is best for players seeking realistic cabinet breakup and nuanced drive at stage or studio volume without hauling a full speaker rig.

Key Features

• Dynamic Speaker Modeling: Faithfully reproduces speaker breakup, cone cry, and drive dynamics so amp-in-a-box tones feel and respond like a real cabinet.
• Expand Any Modeler: Adds depth and realism to amp-in-a-box modelers by providing professional cabinet and room character underfoot.
• Room Emulation: Includes award-winning room modeling to place your amp tone in a realistic studio or live acoustic environment.
• Pro Mic Selection: Offers 22 cabinets and six microphones to shape tone precisely for different styles and gain structures.
• Studio Effects: Built-in UA effects let you craft finished guitar sounds without additional rack gear or plugins.
• Mobile App Customization: A full-featured mobile app provides deep editing, presets, and quick tweaks on the fly.

Who It's For

The OX Stomp is ideal for recording musicians, gigging players using amp simulators, and pedalboard-centric guitarists who need authentic cabinet behavior without hauling a full speaker. It excels when paired with amp-in-a-box pedals and modelers to restore the interaction and breakup you lose from direct outputs.

Players who prefer a simple, transparent IR loader or those who require integrated power amp emulation and reactive load in one unit might look elsewhere; this product focuses on speaker and room emulation plus effects rather than duplicating every element of a full amp head and reactive load system.

Pros & Cons

Pros

• Authentic cabinet breakup and cone character that makes modelers sound more organic.
• Extensive mic and cabinet choices let you dial in studio-ready tones quickly.
• Compact pedal format with powerful effects and a dedicated mobile app for editing.

Cons

• Some customers reported mixed experience with Bluetooth connectivity, so wireless control may be less consistent than wired options.
