I'm giving a full out test run of the clean tones on my Fender Blues Junior amp. I performed the tone stack mod found here:

It hasn't made a huge difference, but I think that combined with the upgraded Jensen speaker that came stock with the NOS edition a solid improvement in tone is achieved. I really like it.
Note: the mod only affects the mids. The knob is allowed to provide less mids than normal from 1-4 and then the normal amount there on up. The tone in general is more similar to a Twin amp with the mod.
Amp settings:
volume - 3
FAT - off
treble - 5
bass - 7
mid - 8
master - 12
reverb - 2
I performed this mod about a month ago. It is extremely simple. It only requires adding one inch long wire connection to two lugs on the mid pot. I'd highly recommend trying it! It is as easy to remove as it was to put in with two touches of solder.
