This is a black Roland Micro Cube guitar amplifier.
The Roland Micro Cube is widely celebrated as one of the best and most popular ultra-compact, battery-powered practice amplifiers ever made. It is legendary for delivering huge, versatile tones and excellent built-in effects from a tiny, take-anywhere package.

It offers 7 distinct COSM amp models and 8 digital effects, including chorus, flanger, phaser, and reverb.
The unit can operate for up to 20 hours on six AA batteries, making it suitable for mobile use

Speaker Size: Because of the compact 5-inch speaker, it lacks low-end response and can "fart out" if you push too much bass at high volumes.
Limited Tweakability: It relies on a single "Tone" knob rather than a 3-band EQ, and you cannot stack multiple modulation effects simultaneously.
Weight: 5.95 lbs, or about 7.5 lbs - with batteries
Dimensions: 9-3/4 inches (W) x 6-13/16 inches (D) x 8-15/16 inches (H)
