A really useful amplifier, can be used with Bluetooth, MP3 player Microphone, guitar and other sound sources. It is well made lightweight and looks attractive. It is very versatile and range of inputs. I use it to play sound from video projections, announcements via microphone and a practice amp for my guitars. The sound is very good but lacks bass ( this is not really a problem a 5" speaker is not going to produce lots of bass notes ) but still sounds very good. The guitar input has a effects button that adds reverb and a separate volume control. Excellent value for money and quick delivery.
