At the risk of being fully incinerated to an unrecognizable pile of ash, IMO there still appear to be an over compressed and distorted quality to the Recto and SLO models, when using a pedal to boost input gain before the amp or using the boost function in the preamp page. I am running all amp parameters at default and particularly low master vol (i.e., 2.0) for the Rectos. 4.03 certainly improved the known issue with 4.01, but these models do not seem to sound as anticipated, as compared to earlier firmware versions or the real-deal sitting in my studio.
I hear what you are talking about, though for me it was in other high gain types like the gainier Dizzy models and Cornfed. I lowered Bias Excursion and I 'think' it was somewhat lessened (someone had mentioned this elsewhere). I'll keep experimenting.
On the flip side, I think low-mid gain amps and the preamp tube models benefited from 4. Lots of models I skipped before are now in my main performance patch, such as the Concert and Nuclear-tone. And I can hear and feel a sizeable difference in different preamp tube settings, particularly in distorting upper frequencies.
