Roland Micro Cube compact guitar amplifier with effects like delay and reverb. Power turns on, but I'm unsure if all functions work. The battery compartment cover is missing, and the strap is broken, so I'm selling it as junk. - Brand: Roland - Model Name: Micro Cube GX - Output: 5W - Effects: Delay, Reverb - Input: 1/4 inch jack - Power Adapter: Included Thank you for looking.
