Universal Audio OX Stomp Speaker Emulator Pedal

The Universal Audio OX Stomp occupies a specific and valuable position in the signal chain: it sits between your preamp source — whether that's a real amp head run into a load box, or an amp-in-a-box modeler — and your recording interface or PA, translating the raw electrical signal into something that sounds like a properly mic'd, room-recorded guitar cabinet. The Dynamic Speaker Modeling at the core of the OX Stomp doesn't just apply an impulse response snapshot; it models the physical behavior of speaker components under load, including the cone breakup, compression, and harmonic content that a real cabinet generates as it's pushed harder. The result is a tonal character that responds to pick dynamics and playing intensity in a way that static IR-based cab simulators often miss.

The OX Stomp houses 22 cabinet emulations and six microphone models, configurable via UA's Bluetooth mobile app with control over mic placement, blending, and room emulation — the same award-winning room processing found in UA's rack-format OX Amp Top Box. Connectivity is practical for both stage and studio: 1/4-inch I/O handles pedalboard integration, USB-C enables direct DAW recording as an audio interface, and Bluetooth manages the deep parameter control without putting a laptop in your signal path. Build quality reflects UA's professional hardware standards — the enclosure is pedalboard-grade, designed to handle the physical reality of live performance. For guitarists building a direct rig around an amp-in-a-box front end, the OX Stomp provides the cabinet layer that elevates the chain from functional to genuinely studio-competitive.
