I just spent some hours working on my tones for this week, very important rehearsal coming Thursday (note the signature link... please check it out!!) with the drummer we are using for the video session. Here's a quickie guide to what I am doing now (remember that beta testing is more about breaking stuff and finding bugs; not taste testing). Now we are out of beta, I can have fun again and just listen and play!! I am doing the following: Dynamics: Leave at Default after you 'reset' the amp block to load in new default settings. Speaker Motor Drive: 5:00 Everything else is stock default settings. Remember to change your amp type; then change it back to reset the default parameters into your amp block. Then only adjust the above settings and get ready to have fun. Sounds fantastic on EVERYTHING, very bouncy, 3D swirly fun!!! Edit: more detail: Quick update on the OP; just reset the amp blocks (change amp type and then change back) to load in default values). Depending on what version firmware you are coming from; you might have to readjust your MV and Drive settings. (*If you are coming from 4.xx, not so much. If you are coming from 3.xx or earlier, you'll need to listen). Set the "Speaker Drive" to 1.50 In the cab block, change the Speaker Motor Drive to 5.00. Play. Adjust to taste. That's it really. I leave the Dynamics tab all at default now. You can mess with it once you have time, I really feel Cliff's defaults here are dead on. The key to 5.00 is the combination of the new power amp modeling - and adding a little to the speaker drive in the amp block matters to this - and the big MONSTER thing is the Speaker Drive Motor in the cab block. That's the key to all. Focus your time and effort on that (start it at 5.00 though; at volume you'll understand why immediately). The rest is just getting the amps updated with the correct default parameters loaded by changing the amp type.
