Roland This is the PM-03, a personal drum monitor amplifier specifically designed for electronic drums. This model is designed for electronic drums such as V-Drums and features powerful sound despite its compact size. Its slim, vertical design allows for space-saving installation. Upon listing, I have confirmed that sound is produced from both the left and right channels via mono input. Volume and woofer adjustments are also functioning correctly. Overall, there are some minor scratches and scuffs from use, but there are no issues with operation, and it is in a condition suitable for normal use. The included accessories are all shown in the images.
