Well after reading through this thread I discovered a lot of questions I will try and answer the ones I remember? lol,
1. Yes you can use the demo as a plug in. navagate to the overloud folder and copy the dll files into your Sonar default vst folder.
2. there are some limits on the demo. you will get a basic idea how it works but the full version seems easier to understand and operate.
3. I Have used Pod Farm 2.5. TH2 has some better sounding amps than the line 6 collection. better than Revalver too. that is just my opinion. I think this will be the amp modler for everyone else to beat!
4. One thing about this is it acts a lot more like a real amp. When I play through a tube amp there is an interaction that happens that I don't get with amp modlers. well.. that is until now. The TH2 acts a lot like a real amp. This is the thing that really surprised me. feed back palm muting all the interation you get from tubes is there. I think that is the thing that impressed me most.
5. The volume wah pedals will operate independently if you have a midi foot switch/controller
The full version has 999 factory presets and 999 user presets. more than enough to play with. The amps in this are like no other sim out there. Just my opinion
