Universal Audio Ships OX Amp Top Box

Giving guitarists legendary album tones from their existing tube amps, anywhere, at any volume.


SCOTTS VALLEY, CA • January 25th, 2018 — Universal Audio, a leading manufacturer of professional audio recording hardware and software, is proud to announce that OX Amp Top Box is now shipping worldwide.


OX Amp Top Box

OX is a premium reactive load box and guitar recording system, giving guitarists perfectly studio-miked amp sounds from their existing tube amp. OX lets users play and record tube amps in their ideal sweet spots — from the edge-of-breakup to fully cranked — with perfect dynamics at any volume level, and with stunning mic, room, and speaker cabinet emulations at the turn of a knob.

Featuring Universal Audio’s breakthrough Dynamic Room Modeling and Dynamic Speaker Modeling, OX is the first amp recording system to accurately emulate speaker breakup and cone cry — an essential ingredient to organic tube amp tones — generating additional harmonics and sonic complexity when the amp is cranked.

Using OX Amp Top Box, guitarists can quickly audition a range of expert cabinet/mic/room combinations — and may find that they never need to mic their tube amp again.

OX Amp Top Box also features a sleek software app for control over all of OX’s parameters via its built-in Wi-Fi, letting guitarists audition, tweak, and store hundreds of cabinet/mic/room presets. Together with a great-sounding tube amp, OX quickly delivers the tastiest album-quality guitar tones of all time.

OX Amp Top Box is now shipping with an estimated street price of $1,299.
