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.
See the bottom of the page for easy instructions on how to change the speaker.
They may partially mask an amps flaws, but the right approach is to make the amp sound great first, then use the speaker to give it that final push in the tone direction you want to go. People who say that a new speaker has cured the Blues Juniors inherent boxy tone simply havent heard a Blues Junior with proper tone stack and power supply mods.
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.
Many people decide to leave it alone after they do the mods.
The farty tone in the bass of a stock Blues Junior is mostly due to poor design decisions in the amp, not flaws in the speaker.
Now I'd like to get a vintage style amp that will do it more justice than my Solid State Raven. Check out ebay, and and I'm sure you will find plenty of options. Cheers, Jeff Thank you guys very much for the info and input. Special mention to the recently launched BJ3 which seems to be a very different animal. Like has been mentioned, they are desinged more for blues and rock players that want an amp that WILL distort at lower volume levels. I happen to love EL84 powered amps in general, but not everyone does. The amp will never have a devine sound, but the new speaker removed the "icepick" treble completely and makes the sound tolerable for jazz: Since there're many debates about differences, supposed superiority of the Green PCBoard ( USA production) vs Creem one( Mexico), it would be nice if posters indicate which BJ version they currently use. Hello, What sets the Blues Jr apart from other Fender amps, is that it's EL84 powered, as opposed to Fender's traditional habit of using 6L6's or 6V6's in the power amp section.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.
