OX AMP TOP BOX

Get Legendary Studio Tones from your Tube Amp

Anywhere, at Any Volume.

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.

Play and record your tube amp in its tonal sweet spot — anywhere, at any volume, with full 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.

A Beautiful Software App

Most guitar products do digital awkwardly. They’re ugly and hard to understand. The OX software app, on the other hand, offers slick, intuitive control over all of OX’s RIG settings via Wi-Fi — letting you tweak, store and recall hundreds of presets from your iPad or Mac. You can then save your six favorite tones onto OX’s front-panel RIG knob for instant recall in the studio or at a gig.

All The Right Connections

Not only does OX Amp Top Box feature a front-panel headphone jack for silent practice with your cranked tube amp, it also sports a bevy of connections for all kinds of recording and live workflows. Stereo S/PDIF digital outputs via RCA and optical TOSLINK, as well as balanced TRS stereo line outputs with front panel level control, give you the necessary connections for studio monitors, DAW, or live mixing console inputs.

“I can use OX on the most critical piece of music and be 100% happy. The UA team knocked it out of the park with this genius piece of gear. It’s perfect for the hobbyist in a bedroom, to the highest professional environment, be it studio or stage. Yes, OX is that good!”
– Lyle Workman(Beck, Sting)

“OX does not disappoint. The room mics give your recorded tones character and realism, and the delays and the plate reverb sound expensive. It's easy to use, yet deep, and most importantly, fun. UA has hit it out of the park with OX!”
– Pete Thorn(Don Henley, Melissa Etheridge)

“OX is a true game changer. New uses for it literally pop into my head every day. It’s head-and-shoulders above any product of its kind. For any guitarist who records his own tracks, OX is essential!”
– Josh Smith(Taylor Hicks, Raphael Saadiq)
