OX Stomp Dynamic Speaker Emulator
Item #: GPMOXSTP | UPC: —
Get album-ready guitar tone anywhere. OX Stomp drops Universal Audio’s renowned Dynamic Speaker Modeling into a pedalboard-friendly format, giving your amp-in-a-box or modeler the feel of a perfectly mic’d cabinet—complete with authentic speaker breakup, cone cry, and room ambience. Choose from curated Rigs that pair classic 1x10, 1x12, 2x12, 4x10, and 4x12 cabinets with sought-after dynamic, condenser, and ribbon mics, then shape the result with studio-grade effects including genuine 1176 compression, plate reverb, stereo delay, and flexible EQ. The six-position Rig knob and assignable footswitches make scene changes instant, so live sets and studio sessions stay focused on playing, not menu diving. Stereo I/O, analog dry through, and buffered bypass keep your signal clean, while the UAFX Control app opens deeper editing for mic choice and placement, room level, EQ per mic, and more. OX Stomp is instrument/line-level only (not a load box), and runs on a modern 9V DC, 400 mA, center-negative supply. If you want three-dimensional cabinet realism and quick, recallable workflows without static IRs, this pedal is the upgrade.
UAFX Series — Universal Audio’s next-gen pedals combine decades of studio expertise with road-ready hardware, mobile control, and silent switching.
