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.
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.
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.
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.
The first amplifiers made in-house by Fender is the Woodie series, built in 1946 through 1948.
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.
Leo Fender began building guitar amps before he started manufacturing guitars.
The first of these amps were the K&F models, which were produced between 19.
The switch to the cream-colored boards reflects the change in where the amps were manufactured, from USA to Mexico.
