Everything has already been said so just a few words about its power.
For a night in a small room or a bar is more than enough with knob 2 or 3.
Despite its specificity "blues" ... I find it relatively versatile (except perhaps for metal??)

UTILIZATION

Easier it is not possible.
But to find his own sound to play with the volume and master.
To get a good sound ... I would say plug a guitar properly ... and play it correctly ... I'm kidding of course, but on this amp it is hard not to have a good sound.

SOUNDS

Originally this was fine.
Now mounted with an old Jensen ... this is perfect.
From clean to crunch ... yum.
For I will add distortion pedal.
I rather play blues or rock and it was the amp that I had.
I often have the opportunity to try other amp (lamp of course) and I have 3 others, but 99% of my time playing ... it is on the Junior.

OVERALL OPINION

I have since 3 years now.
I had other amps before and even now.
It is simple, it sounds, it is powerful.
I could redo this by choice because for me, there is more choice => This is the BJ
