Sorry I've been away from the PC for a few days...thanks again for your compliments and suggestions! They are much appreciated!
synkotron - I'm not sure what the difference is between GR4 and 5. But before S-Gear, GR4 was my main amp sim. I've never tried TH2. Guess I'll have to check it out.
My S-Gear is a few years old and I just had to register it online. I update it now and then because they always add a new amp or effect. I guess the licensing has some new options. I don't iLok so I'm glad I didn't have to deal with that.
As for the mastering, I bounced the final mix to stereo and opened a new Sonar Project. I used T-Racks S3...I loaded it with a Classic Compressor (set to slow compress) then the EQ1 (using the Vintage Mix Preset) then the Classic Compressor again (Set to Fast Compress) and then the Classic Clipper to keep it from distorting.
I usually have to go back and turn certain things up or down in the mix after mastering, so I probably get it after 3 or 4 tries.
Occasionally I'll use a little reverb on the mix if it's too dry or brittle...and I might use different EQ's that come with Sonar if I can't get what I want with the T-Racks....While I try to stick with a basic setup for mixing and mastering, it never fails, every mix is different even if all the parts are similar.
Hope this helps!
