1950s Fender Tweed Harvard “Mystery Amp!” So the only thing that we know is original to this amp is the chassis whose serial number dates to 1957; Everything else has been replaced or rebuilt. That being said it looks and sounds every bit as good as the real thing! Professionally built lacquered tweed cab fitted with a vintage Jensen P12R dated to 1960. There’s a “repro” cabinet label stamped “FL” which would date to the amp to December of 1956. All caps, pots, resistors and transformers are new. If you’re looking for vintage look and sound for a fraction of the price, this is the amp for you!
