It’s some special sauce for your tube amp. Universal Audio’s new OX Amp Top Box sits atop your amp and aids in recording and sound.

The concept: go anywhere, allow you to record at any volume (from off to quiet to really loud), and then model various mic and speaker cabinet emulations at what UA calls “studio quality,” with all the processing you need (EQ, compression, delay, reverb).

And you get Universal Audio’s expertise in modeling all this stuff in a standalone box, rather than lugging along a computer. That suggests a new direction for where UA are going with their technology.

Full specs:

Premium, no-compromise analog reactive load box for tube guitar amps
Five finely-tuned guitar amp attenuation levels — from off, to whisper quiet,
to full band volume
Front-panel “Rig” control for instant, album-quality mic and speaker cabinet emulations
UA Dynamic Speaker Modeling faithfully emulates speaker breakup and cone cry
World-class Universal Audio EQ, compression, delay, and reverb effects built-in
Selectable 4, 8, and 16-Ohm operation
Front-panel Headphone out for silent practice with cranked tones
Balanced TRS line outs, and S/PDIF digital output for recording
Pair with OX mobile or desktop app over Wi-Fi for editing and saving presets

Ships toward end of the year for US$1299 street.

    saw the video, read the note, don’t have ANY clue what this very expensive box does. it’s an attenuator with built-in speaker modelling for recording at the same time? the idea is interesting. but way too little info for knowing how good or practical it is.

      CDM has decided to just regurgitate press releases. Sad!

      We can go to Synthtopia for this type of worthless “content.”

        Joshua, this is from Newswire, which is both a CDM subset now and exactly what you stated. News in our world is typically press releases about products, trade shows and so on…

  • This is a solution to a problem that doesn’t exist.
