Here's what Orange says about the Crush Mini Combo:

OUR TINIEST AMP PACKS A BIG PUNCH!
The Orange Crush Mini is designed to give you classic Orange tone in a small, lightweight package. Whether you’re jamming in your bedroom or warning up backstage, the Crush Mini is the perfect companion.

The simple controls give you access to all kinds of classic sounds. Crank up the Gain for heavy distortion or dial in clean and crunch tones by backing off the Gain and turning the Volume up. A quick tweak of the Shape control (anticlockwise for more mids, clockwise for more scooped) and you’re ready to rock!

Another exciting feature of the Crush Mini is the Speaker Output (8 Ohms minimum). Hook this up to pretty much any speaker cabinet and get ready for a surprisingly big sound!

The Crush Mini features a built-in tuner, as well as a headphone output that mutes the speaker for silent practice. You can also play along to your favourite tracks using the Aux In.

Powered by a 9V battery (included) or an external 9V DC adapter (centre negative), the Crush Mini switches on automatically when you plug in your guitar.

VERSATILE, SIMPLE CONTROLS
A whole lotta tone in three controls. Adjust the Gain and Volume to get any sound, from clean and clear to high-gain and heavy. The Shape control quickly changes the midrange character from mega-thick to super-scooped – and everything in between.

SPEAKER OUTPUT
Turn your Crush Mini into an amp head by hooking up a speaker cabinet to the Speaker output (8 Ohms minimum).

HEADPHONE OUTPUT
Connecting headphones disengages the speaker output for silent practice.

AUX IN
Play along to your music with the Aux In, perfect for practice.

BUILT-IN TUNER
A simple, easy to read, built-in tuner makes the Crush Mini a great all-in-one amplifier.
