=================================

Any tube swaps you might do could allow for more headroom and perhaps allow 
the amp to "do it's thing" better before the feedback monster comes a 
calling. But the swaps will not make it a different amp or give it a 
different "tone," whatever that means. What mic are you using? That will 
make a difference. If you're using a high-output bullet-style mic such as a 
JT-30 or Shure 520, I'd suggest either two 12AY7 preamp tubes or two 12AU7 
preamp tubes. Same with a 545S. I know, though, that BBQ Bob M., doesn't 
swap any - I hope that he'll add his 2 cents to the conversation. If you're 
using a Shure SM57 or 58, you may not need to swap out any tubes at all.
Also, as far as the Pro Junior being a "practice amp," keep in mind that 
this is a VERY loud amp for its size. From 1996-98 I used to play bar-room 
gigs with mine unmiked .... and that was in a band with a guitarist (who 
used a Blues Junior), bass and drums (and I wasn't a very resonant player 
then; I reckon I could get even more volume out of it now). In practical 
terms, my Pro Junior didn't seem to me to be any less loud than my 
guitar-playing buddy's Blues Junior.
