The Blues Junior is a professional tube guitar amplifier introduced in 1995 by the Fender company.
It is aimed at achieving the warm, tube-driven tone common in many styles of American blues and blues rock dating back to the 1950s, while remaining both portable and affordable. Fender frequently releases limited editions of the Blues Junior. All have the same electronic components and specifications but have cosmetic changes and often a different speaker, at varying prices.
Like many Fender amplifiers (particularly in the Hot Rod series), many limited edition versions of the Blues Junior have been manufactured since its introduction in 1995. The original circuit board underwent a major redesign in 2001, when production moved from the US to Mexico.
