Universal Audio OX Stomp

Building upon the success of our award-winning OX Amp Top Box, the OX Stomp Dynamic Speaker Emulator pedal is a game-changer for "amp-in-a-box" enthusiasts. It brings a professional studio's worth of authentic guitar cabinet tones, microphones, room simulations, and high-quality effects right to your feet.

Bid farewell to lifeless Impulse Response (IR) systems.

UA's revolutionary Dynamic Speaker Modeling goes beyond one-dimensional captures, faithfully reproducing speaker breakup, drive, and cone cry. The result is a rich tapestry of harmonics and sonic intricacies that rival the experience of a meticulously studio-miked speaker cabinet.

Prepare for an immersive room emulation experience.

In addition to expertly positioned close condenser, dynamic, and ribbon microphones on your cabinets, OX Stomp is the sole effects pedal offering a comprehensive selection of room microphones equipped with Dynamic Room Modeling. This means you can truly feel the rush of air as you record your cranked amplifier in a world-class tracking room.

Enhance the sonic possibilities of any amp-in-a-box modeler.

Whether you rely on a UAFX amp emulator pedal, other popular amp modelers, multi-effects units, profilers, or even your preferred amp's preamp line out, OX Stomp provides access to over 100 meticulously curated RIG setups. This ensures that you have access to inspiring tones suitable for any amp type or music genre right out of the box.*

Indulge in studio-grade effects.

Beyond its microphone and speaker cabinet modeling capabilities, OX Stomp empowers you to sculpt mesmerizing guitar tones with UA's renowned effects, including authentic 1176 compression, plate reverb, chorus, flange, three distinct delay types, and a four-band EQ with high and low-cut filters.

Tailor your OX Stomp experience with a feature-rich mobile app.

Through the UAFX Control app, you can effortlessly swap cabinets and microphones, fine-tune effects, assign RIG presets, and configure footswitches for seamless sound and effect toggling. It's like having a pro studio's tonal arsenal right on your pedalboard.
