OX is a premium reactive load box and guitar recording system, giving you perfectly studio-miked amp sounds from your favorite tube amp. OX lets you play and record your amp in its sweet spots - from huge clean tones and edge-of-breakup to fully cranked - at any volume level, and with mic, room, and speaker cabinet emulations at the turn of a knob.
Featuring Universal Audio's breakthrough Dynamic Speaker Modeling, OX is the first system to accurately emulate speaker drive, breakup, and cone cry - making it the world's finest speaker attenuator and guitar amp recording solution.
The World's Best Reactive Load Box
With decades of analog hardware engineering expertise, Universal Audio's dream team of engineers set out to design a reactive load box that retains the tone, dynamics, and feel of your tube amp - no matter how much it's attenuated. The goal was for your tube amp to "see" OX as an actual speaker - with continuously variable impedance and response - so you don't lose a drop of tone or playing dynamics.
A Complete Guitar Recording System
OX's front-panel, six-position RIG control allows you to quickly choose from complete setups - including emulated speaker cabinets, close mics, ambient room mics, and up to four simultaneous studio effects. OX is also the only guitar recording system to offer a complete selection of expertly placed room mics, giving you the authentic experience of pushing air while recording your cranked amp in a world-class tracking room.
Dynamic Speaker Modeling
UA's groundbreaking Dynamic Speaker Modeling faithfully emulates speaker breakup, drive, and cone cry - an essential ingredient to authentic tube amp tones. Using the Speaker Breakup knob in the OX app, you can control the harmonics and sonic complexity that occurs only at certain frequencies and volume levels on various speakers - far beyond a static Impulse Response system - giving you the same sonic phenomenon that occurs with a real speaker cabinet.
