This is a set of the VOX AP-BM Brian May signature amPlug Brian May, the VOX amPlug2 Cabinet AP2-CAB, and a cable (please refrain from purchasing separately). I purchased this a few days ago and have stored it since. I've only used it indoors. I've confirmed that it produces sound. Please check the VOX website or YouTube for specifications and sound samples. An adapter is not included, but I will include batteries. You can have fun playing with the Brian May sound (you can feel like you're on stage at Wembley Stadium). Also, it has the drum rhythm of "We Will Rock You," so you can play and sing along, becoming a one-person Queen (please do so at your own risk). It's a beautiful item, but please understand that it is used. Thank you.
