I have a modded 5K (five knob) Galaxie 10 that's pretty cool. But to be honest, unmodded (mine was given to me) it was extremely nothing special.
I've played the VJr and think it's the same amp with fewer controls. They don't suck, but believe me when I say they totally lack the mojo of my Black Face Princeton Reverb. I know that's not a fair comparison, but it's my go to small amp (along with a great sounding Sano). The Epi amps are not even in the ballpark of a real killer amp IMHO. For a hundo, not bad.
If you're down to get into some soldering though... they get much better (I prefer my modded 5KGX10 to my vintage AC15 in all but lead guitar applications).
NO EXCUSES, THE OUTPUT TRANSFORMER MUST GO!
