Cliff-
Are the two ODS models based on the real amp or based off of schematics only (ie, like the two Dumble models on the previous generation)? In my limited time with the Standard I definitely preferred the HAD version; it was much livelier!
Also, what are the chances of getting the Guytron GT100 preamp on the II? The schematics are patented and can be found here:

It's mainly an 18watt EL84 Marshall poweramp run full out with a very simple tone stack and a dual-ganged gain pot for the B channel which is then slaved to a 100watt EL34 power section. Obviously you wouldn't need to model the EL34 section since it's only used for volume (the whole poweramp is designed like an old 100watt PA, very clean). In my experience there isn't really anything out there that sounds like the A and B channel on this amp.
