Hey Dave,

update. Your query got me back into these simulators and I can't say why I didn't pursue them more when I started playing around with them, but decided to give them another go and upgraded to vs Amplitube 5.5. These things are great! I have spent the night trying the Fender collection. They sound amazing. 

Current hook up has me running my pc into my PA head. Glad you brought this up. 

Good luck with your setup.
