So I picked up a pair of EV 15" PA speakers to use instead of my 412.  HUGE improvement, even over what was already sounding good.  Now I have the Axe cab models at my disposal, and I've found a couple of ones that I really like, but will probably stick with just one, the JCM2000 cab, for the sake of having a slightly more consistant sound across gain levels.  More like having a multichannel amp and not bouncing around tone-wise too much.  The Axe cab models seem to complete the equation.  I have really nice bounce and feel.  Feels like a tube amp.  I was able to duplicate the crunch channel from my TSL, and I really can't tell the difference unless I'm actually looking at the unit and know it isn't a Marshall.  Found some really nice high gain rhythm using the CAE 3+ Lead model, and the recto is a recto.  I still have some work to do in making custom cables for my expression pedals, but I should have that done today.

My Avatar 412 is going on Craigslist.  I have no need for it anymore.  My on stage sound is now the exact same thing coming from the FOH.
