The Blues Junior is a tubeguitar amplifier introduced in 1990 by the Fender Musical Instrument Corporation. 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[1][failed verification][non-primary source needed] and specifications but have cosmetic changes and often a different speaker, at varying prices. 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.[2][non-primary source needed] The Fender Blues Junior was introduced after the Fender Pro Junior, but has entirely different circuitry and uses two EL84 output tubes rather than Pro's four, although both are rated at 15 watts.

Varying editions[edit]
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. The earlier circuit boards are green in color and are noted for a 'darker,' more bass-inflected tone. 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.[3][non-primary source needed]
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 'Blonde' and 'Brown Tolex' Blues Juniors feature traditional Fender Tolex upholstery in their respective colors, while the Sunburst Ash edition features an ash cabinet with a sunburst stain. One edition was issued with a forest green colored cabinet, had a United States flag on the cloth speaker grille, and had United States Air Force markings detailed on the cabinet in yellow.[citation needed]
The standard Blues Junior is dressed like a traditional black Fender amplifier, with black Tolex upholstery and a silver cloth speaker grille.
Although they differ in their external visual aesthetic, all variants of the Blues Junior for a given year are produced with the same electronics, apart from the speaker/driver. Limited editions may use varying driver models, such as the Jensen C12N found in the NOS Lacquered Tweed Blues Junior or the Jensen P12R found in the Relic edition. Fender does not always include these limited edition versions in their updated catalogs (or on their website) either because too few were produced (only a few hundred in some cases) or perhaps because of exclusive retailer agreements.[citation needed]
Blues Junior revision history[edit]
Fender introduced the Blues Junior in 1995 and has revised and updated the amp periodically since then. The Blues Junior history can be divided into two major categories: the early amps with green circuit boards and the later ones with cream-colored boards. The switch to the cream-colored boards reflects the change in where the amps were manufactured, from USA to Mexico. The cream-colored board is laid out entirely differently from the green board. The biggest change is the reworked reverb circuit. The older amps tend to sound darker, while the new ones are brighter with more emphasis on treble tones.[citation needed]
The table Below details the revision dates and the changes made on those dates.[citation needed]
Dating a Blues Junior[edit]
Fender adopted a two-letter dating code in 1990. The code can be found on the Quality Assurance label located inside the cabinet. The label is often located on the bottom next to the reverb tank, sometimes it is placed on the side. The codes can be handwritten, which can occasionally make the letters hard to decipher.
Fender discontinued date codes in 2003. There is no reliable way to date 2003â2005 amps other than to ask Fender customer support to look up the date from the serial number. Amps made in 2006 have a small metal 'Fender 60th Anniversary' button on the back plate. Amps from 2007 are undistinguished.
Blues Junior III[edit]
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.[4]
Tube complement and bias setting[edit]
A set of three matched Groove Tubes 12AX7 preamp tubes and two matched Groove Tubes EL84 power tubes, graded according to Fender's specifications, are used in all factory Blues Juniors. The Blues Junior uses a nonadjustable power tube bias (no way to vary the bias point), but it is fairly 'hot' and can accommodate most matched pairs on the market. However, because they 'run hot', a common modification is to add a bias trim to enable adjustments to the idle current when switching tubes.[citation needed]
