Fender Vibro Champ. The serial number dates this around 1978 - but I have not checked transformer dates. Very clean and in above average condition. My amp tech says that he thinks no one have ever put a soldering iron to this amp (but that is only his opinion). He also says that he thinks the valves are original. I didn`t want to change them because I would like to sell this as an all-original piece. Naturally it would be good for a re valve at some time. (stock number 3316)
