Amps made in 2006 have a small metal "Fender 60th Anniversary" button on the back plate. In 2010 Fender updated their line of hot rod model amps and released the "Blues Junior III," adding many physical changes to the standard black tolex model.
Notable differences include the Fender "lightning bolt" speaker, "sparkle" circuit modification, rattle-reducing shock absorbers, set-screw "chicken head" knobs, "dog bone" handle, larger Fender jewel light, black non-reflective control panel, and "Blues Junior" subtext on the logo plate.
Although a serial number is helpful for roughly determining the age of a guitar, this is often not the exact date.
The earlier circuit boards are green in color and are noted for a "darker," more bass-inflected tone.
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.
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.
The Blues Junior is a tube guitar amplifier introduced in 1990 by the Fender Musical Instrument Corporation.
