Summer NAMM 2017: Universal Audio’s Ox gets “perfect tone from tube guitar amps at any volume”

SUMMER NAMM 2017: Universal Audio has been releasing an increasing number of guitar products of late, and now the company has expanded into physical guitar gear with the Ox Amp Top Box.

The Ox is a reactive load box and attenuator, allowing guitarists to play and record tube amps at any volume, utilising “instant album-quality” mic, room and speaker cabinet emulations onboard the unit.

Rig presets offer mic and studio emulations, while Dynamic Speaker Modelling emulates speaker break-up and cone cry, for convincing cranked amp tones.

Colour us intrigued. The Ox is due to land this winter, clocking in at $1,299. See Universal Audio for more info.
