So-- Does a guitar amp that is being sold in the US need a UL approval? As far as I know, if it plugs into the wall, and it is going to be sold for a profit, it need this basic approval. Of course this dosent include DIY items and kit's, but I look at the backs of many of the Boutique amps and,, Na Da! This voilation of the law seems to be more rampit in the guitar amp busness, perhaps because testing and approval costs 1000's of dollars, and there is kind of a renigade attitude in the amp busness anyway. I would not like to be a shop owner who took on one of these low volume brands only to be sucked into a law suit when someone's house burned. I would be intrested in reading peoples thoughts.
