I have never taken it outside. It was used completely at home. ORANGE Crush 15 R guitar amplifier with reverb and equalization functions. There is no scratchy noise and it works properly. It also comes with an adapter for a three-prong outlet, so you can use it right away. The top part has some color remaining from a live house pass that was stuck there. It is not sticky. As a bonus, I will also include an ORANGE cable. - Brand: ORANGE - Model Name: Crush 15 R - Functions: Reverb, Equalization - Controls: Gain, Master, Level, Volume, Low, Mid, High - Power: AC power - Serial Number: C171014142 Thank you for looking.
