From Orange:

Don’t let the size fool you: the Orange Micro Terror packs real valve tone and serious volume into the tiniest of heads. Inspired by the original Terror series, this 20W hybrid amp pairs a single ECC83 (12AX7) valve preamp with a solid-state output stage to deliver everything from crisp cleans to rich, saturated overdrive. Compact enough to sit on a desktop, loud enough to gig with, and portable enough to take anywhere, the Micro Terror is a modern classic for players who want huge sound without the heavy lifting. Plug in and prepare to be surprised.

ECC83 Valve Preamp
Classic Orange tone and touch sensitivity in a miniature head thanks to the ECC83 (12AX7) valve preamp stage.

20 Watts of Hybrid Power
Plenty of clean headroom and crunchy gain, with enough volume to surprise even the most seasoned players.

Auxiliary Input
Plug in your phone or MP3 player to jam along with your favourite tracks — perfect for solo practice.

Ultra-Portable Design
Weighing less than a kilo, this amp is built to travel, anywhere from the bedroom to the backstage.

The Micro Terror might be small, but it’s built to deliver big tone. Its simple layout — Volume, Tone, Gain — keeps things intuitive while still offering huge flexibility across genres. At the heart of its hybrid design is a ECC83 (12AX7) valve preamp, which brings warmth, touch sensitivity and character to your sound. Matched with a 20W solid-state power amp, it’s surprisingly loud, especially when paired with an efficient cab.

An auxiliary input lets you jam along with backing tracks, making it ideal for home practice, studio work, or quick demos. And thanks to its steel construction and carry handle, it’s tough enough for life on the road. The Micro Terror is proof that great things really do come in small packages.
