Fender Blues Junior
I will not focus on make-up variations here. It really doesn't matter much. But I can't be quiet on speaker variations. One more thing to note, in 2001. production of these amps moved from USA to Mexico. Early models of Fender Blues Junior were a bit moody or bassy if you like, and later models were more bright sounding, similar to the great Fender Blues Deluxe.
Standard Fender Blues Junior
Uses Eminence speaker. It sounds perfect with Telecaster and Stratocaster
guitars, but it's a bit bassy for my taste when Gibson
guitars are plugged into it. As of lately, Fender
released new edition called "Blues Junior III",
which replaces the standard one. It has minor changes
over the last one, like front reading text on top panel,
new badge.. etc.
NOS Lacquer Tweed Limited Edition Fender Blues Junior
Features Jensen C12K speaker. It's much brighter than the standard one,
but it very much depends on what sound flavors you prefer. To me,
it's too bright when played with Telecaster or Stratocaster type
guitar, but sounds really nice with Gibson Les Paul and other Gibson
guitars.
Tweed Relic Edition Fender Blues Junior
This one is pretty much the same as the one above, but it's factory aged
and features Jensen P12R speaker.
Fender Blues Junior Texas Red
Features Celestion Vintage 30 speaker. I think this one is actually the
best Fender Blues Junior edition produced to date. This speaker is the most
common upgrade everyone will suggest you. It just sounds right and
powerful. You can play both Gibson and Fender guitars through it, and it
will deliver everything you wished for!
