Not sure if the amp is American or Japanese as the amp plate says American but the speakers are Japanese. Channel 1 works with no issues, but channel 2 has a couple. First off with some scratchy pots but nothing too crazy and a simple clean with contact cleaner should do the trick. The reverb does not work at all and the bright switch on channel 2 switches on and off randomly and on its own. All the eq’s, volumes, distortion, vibrato and chorus all work and sound nice. The side crews are stripped and needs to be looked at. Does not come with a footswitch. Even though it has issues that can be ignored to just get by and play the amp. We are saying that it’s a projects guitar and can not be returned unless it arrives in a different condition then it was sent in. Any questions please feel free to ask
