Used Bose S1 Pro speaker with battery and mains kettle lead. In very good used condition. 3 channels and can be used as a regular powered speaker on the floor, or tipped back, or on its side (acting as a stage monitor) or on a stand (it has a stand socket).
I have used it with acoustic guitar, dynamic mic and backing tracks with a line-in from my iPad or using Bluetooth. Channels 1 and 2 each have reverb and each has a switch for mic, guitar or line-in.
The battery is rated as up to 11 hours, although it's more like 5 hours when turned up loud. Superb quality sound which can cope with smaller gigs comfortably (up to 50 people).
I am selling this due to buying the Bose S1 Pro+
