Unlock Legendary Studio Tones with Your Tube Amp – Anytime, Anywhere

The OX Amp Top Box is a premium reactive load box and guitar recording system that gives you the sound of a perfectly mic’d studio setup with your favorite tube amp. OX allows you to play and record your amp at its ideal settings – from huge clean tones to edge-of-breakup and full-on distortion – at any volume, with mic, room, and speaker cabinet emulation, all at the turn of a knob.

Built with breakthrough Dynamic Speaker Modeling, OX is the first system to faithfully emulate speaker breakup and cone cry at all volume levels, making it the world’s finest reactive load box and recording solution for guitar amps.

Key Benefits

• Play and record your tube amp at its ideal settings, anywhere, at any volume, with full dynamics.
• Quickly select from over 100 stunning Rigs on your iPad or Mac.
• Achieve breathtaking mic and speaker cabinet combinations with the turn of a RIG knob – no miking required.
• Get authentic "edge-of-speaker-damage" tones with speaker breakup and cone cry, along with UA Dynamic Room Modeling.

World’s Best Reactive Load Box

Universal Audio’s team of seasoned engineers created a reactive load box that maintains the tone, dynamics, and "feel" of your tube amp – regardless of how much power you’re attenuating. The goal was for your amp to respond to OX like it would to a real speaker, providing a smooth, continuous impedance and response so you lose none of your tone or playing dynamics.

Complete Guitar Recording System

The front-panel six-position RIG control allows you to quickly select full setups – including simulated cabinets, close mics, room mics, and up to four simultaneous studio effects. OX is the only guitar recording system to offer a full complement of professionally placed ambient mics, giving you the real sense of air movement that happens when recording a cranked amp in a world-class studio.

Dynamic Speaker Modeling

UA’s breakthrough Dynamic Speaker Modeling faithfully emulates speaker breakup and cone cry – essential elements of a true tube amp experience. Using the Speaker Breakup control in the OX app, you can dial in the harmonic complexity that occurs only at certain frequencies and volume levels for various speakers, offering more than static impulse responses, and delivering the same sonic phenomena that happen in a real speaker cabinet.

Beautiful App

Digital versions of guitar products are often clunky, ugly, and hard to understand. The OX app, on the other hand, provides easy, intuitive control over all OX RIG settings via Wi-Fi, allowing you to tweak, save, and recall hundreds of presets from your iPad or Mac. You can save six of your favorite sounds and recall them in the studio or on stage with the front-panel RIG knob.

All the Right Connections

OX Amp Top Box features not only a headphone out for silent practice with your cranked amp, but also a suite of outputs for any kind of recording and live use. Stereo S/PDIF digital outs (RCA) and optical TOSLINK, plus balanced TRS stereo line outs with front-panel level control, provide essential connectivity for studio monitors, DAW inputs, and mixers.
