I originally bought this amp as a portable solution for small jazz gigs with trios/duos. Sadly it does not produce much sound before it starts to break up and I think there are better options on the market as far as this purpose is concerned. However, I have also used it to amplify my nylon-stringed electro-acoustic guitar for which purpose it works very well, even with a full rhythm section in a large concert hall. I would recommend this amp for amplifying electro-acoustic guitars but not for general use with semi-acoustic or solid guitars.
