Universal Audio Ox Amp Top Box

Universal Audio OX Amp Top Box – Studio Quality for Your Tube Amp, at Any Volume

The Universal Audio OX Amp Top Box is a dream tool for anyone who wants to capture the character of a tube amplifier without blowing the room. UA combines a reactive load , world-class cabinet/room modeling , and studio-grade effects in one incredibly user-friendly system.

At its core is the reactive load , which faithfully mimics the behavior of a real speaker cabinet. This allows you to retain the precise feel, compression, and dynamics your amp normally delivers when fully cranked. This allows you to play with the output stage in the sweet spot while maintaining complete control over the volume.

What makes the OX unique is Universal Audio's RIG technology . You get access to a range of high-end cabinet, microphone, and room models , along with flawless UA-quality effects like compression, plate reverb, delay, and EQ. Everything sounds like it came straight from a boutique studio, without any complexity or additional equipment.

Whether you're working through the line outs , SPDIF , or headphone out , the OX consistently delivers high-quality, mix-ready sounds that are instantly usable in every recording. The OX app makes it easy to tweak and save rigs, so you always have your favorite sounds at hand.

Live, the OX is just as impressive: you can let your amp perform as intended, but at perfectly controllable volume , without sacrificing tone or feel. The OX also excels as a silent practice tool—your amp at full power, you with headphones in the middle of a "studio room."

The Universal Audio OX is therefore the ideal choice for guitarists who want to combine studio quality with tube authenticity. Whether you're recording, practicing, or playing live: the OX gets the most out of your amplifier, at any volume, at any time.
