Voici la réponse d'un des plus grands spécialistes du blues junior:
"The USA Blues Juniors are generally referred to as green boards and the made-in-Mexico have a tan or cream-colored board. There are some USA cream boards made in 2001, and some later USA Custom Shop Blues Junior variants that used leftover green boards, so it's better to refer to the board color than the country of origin. The reverb on the green boards does not go through the master volume, which is kind of weird. It's also subject to hum and noise, and it's not particularly strong. Fender corrected that on the cream board.
The other major difference is the tone controls. The green board has an audio-taper treble control and a linear bass control. Consequently, the bass comes on fast and you have to turn the treble past 10 to get any brightness out of the amp. The cream board has the opposite: audio-taper bass and linear treble. So at most normal tone control settings, the cream boards sound much brighter.
If you turn all of the tone controls to max, the amps theoretically sound identical. But because of layout differences, the green board has a subtle roundness or darker color. Neither is better or worse, just a little different.
In terms of construction techniques, component quality, etc., the amps are the same.
There are simple mods to make the green board reverb work like the cream board. I've done hundreds of conversions and sent out hundreds more kits to do the conversion, and there are exactly two customers who preferred the reverb the old, weak and noisy way. Go figure."
