Building on our award-winning OX Amp Top Box, the OX Stomp Dynamic Speaker Emulator pedal offers "amp-in-a-box" modelers a professional studio packed with authentic-sounding guitar cabinets, microphones, room modeling, and studio-quality effects — all at your feet.

• Get three-dimensional, album-ready guitar tones from your amp emulator thanks to Dynamic Speaker Modeling
• Experience stunning speaker, cabinet, and room emulations far beyond typical IR loaders
• Add studio-quality 1176 compression, plate reverb, EQ, modulation, and stereo delay effects for perfectly crafted tones
• Preview, adjust, and save custom presets and more with the UAFX mobile app

Say Goodbye to Static-Sounding IRs
Far beyond the one-dimensional captures of Impulse Response systems, only UA’s groundbreaking Dynamic Speaker Modeling convincingly emulates speaker breakup, drive, and cone cry — delivering harmonics and sonic complexity indistinguishable from a perfectly studio-miked speaker cabinet.

Experience Award-winning Room Emulation
Along with expertly placed close condenser, dynamic, and ribbon microphones on your cabinets, OX Stomp is the only effects pedal to offer a full selection of room microphones with Dynamic Room Modeling. This gives you the authentic experience of pushing air while recording your cranked amp in a world-class tracking room.

Enjoy Studio-Quality Effects
Beyond mic and speaker cabinet modeling, OX Stomp also lets you create stunning guitar sounds with UA effects like genuine 1176 compression, plate reverb, chorus, flange, three delay types, and four-band EQ with high and low-cut filters.

Expand the Tones of any Amp-in-a-Box Modeler
Whether you're using a UAFX amp emulator pedal or other popular amp modelers, multi-effects, or profilers — even your favorite amp's preamp line out — OX Stomp gives you over 100 curated RIG setups, providing inspiring sounds for any amp type or genre, right out of the box.*

Customize your OX Stomp with a Full-Featured Mobile App
With the UAFX Control app, you can easily swap cabinets and microphones, fine-tune effects, assign RIG presets, and configure footswitches to instantly toggle sounds and/or effects, delivering a pro studio’s worth of tones on your pedalboard.
