So, I’ve got this old Twin I’d like to turn into an upright bass, but I’m not really sure what I’ve got. I bought it back in the 90’s and the power transformer and chassis indicate it is a 1971 model, but it has a blackface and those were discontinued in 1967. I think it may be a blackface conversion of a 1971. The original speakers have been replaced with EVM-12L’s, so it weighs over 100 lbs and is ridiculously loud and clean sounding. I’m really not sure what I’ve got or what it’s worth. Anyone care to venture a guess?
