Okay after long delay, more thorough analysis. My reference point is an old Blues Jr. NOS Tweed w. Jensen.
With all the extra features (3 voices, line-out, headphone out, FX loop, better volume control, smaller, lightweight), if it sounded almost as good as the BJ, it would have been worth it. But it sounds, A LOT better.
- This just sounds a lot better: Fendery-cleans, dirt, everything in between.
- Better tone at lower volume. I'm able to let the amp do more of the work (gain). My gain stacking has been easier to dial in (Tumnus->Timmy)
- All 3 channels sound great, although I've been mostly in the blonde and somewhat on the BF.
- The line out works really well. Much easier to get to my "real" tone in my DAW than via pedalboard->Amplitube (where I was using a virtual Princeton). Probably more of an issue of me learning the nuances of Amplitube, but easier is easier.
- Headphone out sounds better than anything I've used in the past (mostly cheap practice amps)
- EQ is much more responsive, not even counting the 3 channels
- My only other solid states have been like those $130 practice amps. There's really no comparison there.
Not even once has it crossed my mind that I wish I got the Princeton or Supro, the other amps I was looking at.
Thanks everyone for the great advice.
