Roland Mobile Cube Used, but I think it's in good condition. I have confirmed power-on and sound output using batteries, and operation has been verified. The power cord is not included; please purchase separately. It can also be operated with batteries. I will include a printed instruction manual from the manufacturer's website. The Roland Mobile Cube is a multi-functional portable PA for microphones, instruments, and guitars. - Brand: Roland - Model Name: Mobile Cube - Features: Microphone input, for keyboards/instruments/guitars, AUX input - Controls: Volume, Chorus, Tone, Clean/Overdrive, Distortion - Stereo Output: Equipped with stereo output It can also be used with dry cell batteries, allowing use where there is no power source. You can use a microphone, keyboard, and AUX input, so you can also have a session with a sound source. You can use the center cancel function during a session to remove the main sound and add your own instrument. It's a very user-friendly amp & simple PA. How about it?
