Product Overview

Go Beyond Static IRs with Dynamic Speaker Modeling and Room Alchemy

While standard digital impulse responses (IRs) provide a snapshot of a guitar cabinet in a single moment, they lack the organic movement, compression, and three-dimensional reaction of real physical speakers. The Universal Audio UAFX OX Stomp Dynamic Speaker Emulator redefines direct guitar tone. Powered by UA's heavy-duty dual-engine modeling, OX Stomp convincingly captures real-world speaker breakup, dynamic drive, cone cry, and complex harmonic impedance. It acts not as a static filter, but as a living, breathing mechanical enclosure reacting dynamically to your playing volume.

Designed strictly for instrument-level and line-level signals, OX Stomp acts as the ultimate processing final stage for your modern pedalboard. Pair it with your favorite amp modelers, preamp pedals, or multi-effects engines, turn off their internal cab simulation, and let OX Stomp handle the rest—delivering deep, mix-ready tones indistinguishable from an isolated tracking room.

Product Description

A Vault of 22 Iconic Cabinets and 6 Studio Microphones:

OX Stomp gives you instant access to a vast, curated collection of 22 legendary vintage and modern speaker enclosures. From mid-’50s small American tweed combos and legendary British 2x12 setups with Celestion Silver Bulldogs, to massive, heavy-hitting boutique 4x12 cabs loaded with vintage Greenbacks or Vintage 30s, the selection satisfies any genre.

You can mix, match, and dual-mic these cabinets using six pristine studio microphones (Dynamic, Condenser, and Ribbon variants). Dedicated physical toggle switches and discrete Mic 1 and Mic 2 level knobs on the faceplate allow you to independently position and blend two mics simultaneously, creating thick, expansive stereo configurations or punchy, phase-aligned mono tracks.

Award-Winning Dynamic Room Modeling:

The secret weapon of the OX ecosystem is its proprietary Dynamic Room Modeling, managed by the physical Room knob. This control adjusts the level of carefully placed ambient room microphones inside a world-class tracking environment. It lets you go from an intimate, completely dry direct sound to the immersive sensation of moving real air inside a premium acoustic space. It eliminates the sterile, "closed-in" feel common with direct modelers, giving you a natural feel whether you are playing through studio monitors, stage PAs, or headphones.

Onboard Studio-Quality Outboard Rack Effects:

Beyond speaker cabinet and microphone physics, OX Stomp acts as a complete outboard processing rack. It includes four independent blocks of masterfully coded Universal Audio digital studio effects:

• Genuine UA 1176 Compression: Tighten up transients, add infinite sustain, and glue your guitar tones together using the definitive FET studio compressor circuit.

• Premium Plate Reverb: Envelop your direct sounds in a lush, smooth, three-dimensional studio-plate cloud.

• Pro Stereo Delay Suite: Dial in massive ambient fields with specialized Dual, Crossover, and Ping-Pong delays featuring independent time control per channel.

• 4-Band Parametric EQ: Sculpt your final tone to perfection with integrated high- and low-cut filters tailored for pro mixing consoles.

Bluetooth Editing, Real-Time MIDI, and USB Capabilities:

With 100 pre-configured RIG combinations right out of the box, you can assign your favorite six setups directly to the hardware RIG selector knob for quick recall. Connecting the pedal via Bluetooth or hardwired USB to the UAFX Control mobile app unlocks total parameter customization, allowing you to swap cabs, reposition mics, tweak the deep settings of the effects blocks, and configure the dual-footswitch routing matrix. Additionally, its advanced USB-to-MIDI capabilities allow the pedal to integrate seamlessly into modern programmable switching rigs for instant MIDI preset changes on stage.

(Note: OX Stomp is not a load box or an attenuator. Do not connect a powered tube or solid-state amplifier head directly to its inputs.)
