Ok so I'm a solo performer and my main PA is in for repair so bought this for back up. I only use 3 channels which are vocals Stratocaster guitar and drum machine. Just tested it today indoors and wound the volume up. Although I'm only using it at 140 watts per side at 8 ohms set up, its still very loud. Very good sound quality and very quiet fan. Set up was a breeze. On board FX very good too. Amp is very light compared to my Peavey XR 800f. I am honestly amazed at the sound and build quality for such a lightweight amp. Cant wait to try it out at a gig. Ok its probably not going to fill a stadium with sound but for a soloist or a duo in a pub or club it will be fine I am sure.
