The Orange Micro Crush is a small, 9 volt battery powered amplifier. The amplifier is rated at 3 watts of output power and the orange covered wood and metal enclosure contains a 4 Inch speaker.
Here is a rear view of the orange micro crush guitar amplifier. The rear panel contains a 3.5mm headphone jack and input jack for using an AC power adapter.
The 9 Volt Battery is inserted into the bottom of the amplifier. This amplifier works best with the AC Adapter connected. The AC adapter provides a noticeable volume increase over the battery. A typical 9 volt alkaline battery will not last very long in this amp so I would recommend a rechargeable Li-ion battery and charger.
