This is an Orange Crush 20rt guitar amplifier. It has never been taken outside. I think it's a perfect amp for practicing at home, with a built-in tuner. The following is an excerpt from the product HP: The Crush 20, a digital amplifier from "ORANGE" that is perfect for practicing at home. ORANGE's circuitry faithfully translates picking nuances into sound, and has an amazing responsiveness. The Clean/Dirty switch on the control panel allows you to switch between a brilliant clean sound and a high-gain metal sound (can also be switched with a separately sold footswitch). It is equipped with a chromatic tuner, so you can tune just by connecting it to the amp. ■ Guitar Amplifier ■ Combo type ■ Output: 20W ■ Speaker: Custom 8-inch speaker ■ Controls: Clean Volume, Dirty Gain, Bass, Middle, Treble, Dirty Volume, Channel Selector SW, AUX IN, Phone Out, Chromatic Tuner, Reverb, Footswitch Jack ■ A model that adds reverb and chromatic tuner functions to the CRUSH 20 ■ Dimensions: 37.5 x 32.5 x 19.7cm ■ Weight: 7.2kg Thank you for looking.
