The Fender Blues Junior is most similar to the Fender Blues Deluxe, which adds a "drive" channel, an effects loop, and uses 6L6GC output tubes for 40 watts of rated output.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 Blues Junior is a 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.
The standard Blues Junior is dressed like a traditional black Fender amplifier, with black Tolex upholstery and a silver cloth speaker grille.
Lacquered Tweed editions, as the name implies, feature a cabinet upholstered with a lacquered tweed fabric.
Some of these have been artificially aged from the factory and are known as Lacquered Tweed "Relic" editions.
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.
Many green board models have excessive noise in the reverb circuit, as the signal is inserted into the reverb after the master volume.
The later circuit boards are cream or tan colored and sound "brighter" or more treble-oriented, with the reverb situated before the Master volume.
The original circuit board underwent a major redesign in 2001, when production moved from the US to Mexico.
The earlier circuit boards are green in color and are noted for a "darker," more bass-inflected tone.
